The smaller the numerator, the smaller the fraction, and the larger the numerator, the larger the fr

No, the condition is missing, it should be said that in the case of the same denominator, the smaller the numerator, the smaller the fraction, and the larger the numerator, the larger the fraction. For example, 2 out of 5 is greater than 1 out of 5.

Fraction size comparison refers to the fact that for fractions with the same denominator or numerator, they can be compared according to the method of comparing the size of fractions with the same denominator or the same numerator. For fractions where the denominator and numerator are not the same, the method of first passing through and then comparing the size is usually used.

Extended Information: Common Fraction Comparison Methods:

1. Homogenization molecular method.

First, two fractions with different molecules are converted into two fractions with the same molecule, and then the two fractions with the same numerator are compared, and the fraction with the smaller denominator is larger.

2. Fractional method.

Convert the two fractions into decimal places and compare them.

3. Bridging method.

Between the two scores to be compared, find an intermediate score and compare the magnitude of the two scores according to the relationship between the two scores and the middle score.

4. Differential law method.

According to "two true fractions where the difference between the numerator and the denominator is equal, the numerator plus the denominator gives a larger fraction; The difference between the numerator and the denominator is equal to the two false fractions, and the numerator plus the denominator gives the larger fraction and the smaller fraction compares the magnitude of the two fractions.

5. Cross-multiplication.

The product of multiplying the numerator of the first fraction by the denominator of the second fraction is taken as the relative value of the first fraction; The product of the numerator of the second fraction and the denominator of the first fraction is taken as the relative value of the second fraction, and the fraction with the larger relative value is larger.

6. Compare the reciprocal method.

Compare the magnitude of two fractions by comparing the size of the reciprocal of the two fractions. The lower reciprocal fraction, the larger original fraction; The larger the reciprocal fraction, the smaller the original fraction.

7. Division.

Divide the first fraction by the second fraction, if the quotient is less than 1, the first fraction is smaller; If the quotient is greater than 1, the first fraction is larger; If the quotient is equal to 1, then the two fractions are equal.

Mistake. The analysis process is as follows:

The smaller the numerator, the smaller the fraction, and the larger the numerator, the larger the fraction. There is a premise that the smaller the positive fraction numerator with the same denominator, the smaller the fraction, and the larger the numerator, the larger the fraction.

In the absence of preconditions, it is generally said that the smaller the numerator, the smaller the fraction, and the larger the numerator, the larger the fraction. is a false proposition.

Extended Information: Here's how to compare the size of the scores:

1. In the case of the same numerator, the smaller the denominator, the larger the score.

For example: 1 2> 1 3

2. When the denominator is the same, the larger the numerator, the larger the score.

For example: 2 3> 1 3

3. If the numerator and denominator are not the same, first pass the fraction, and then compare the size.

For example: 1 3 (=4 12) > 1 4 (=3 12).

For two true fractions, if the numerator and denominator are the same number apart, then the fraction with both the numerator and denominator is larger is larger.

For two false fractions, if the numerator and denominator are the same number apart, the fraction with both the numerator and denominator is smaller is larger.

Wrong. The magnitude of a fraction is determined by both the numerator and the denominator.

With the same denominator, the larger the numerator, the larger the fraction; The smaller the numerator, the smaller the fraction.

On the premise that the denominator is the same, the smaller the numerator, the smaller the fraction, and the larger the numerator, the larger the fraction.

A condition is dropped, the denominator remains the same, the smaller the numerator, the smaller the fraction, and the larger the numerator, the larger the fraction.

The method of the size of the two fractions of the same molecule:DenominatorThe larger it is, the smaller the fraction, and the smaller the denominator, the larger the fraction.

The simplest fraction comparison size is the comparison size between fractions with the same denominator. Compare molecular sizes directly. The larger the numerator, the greater the value of the fraction; Conversely, the smaller the numerator, the smaller the score. Of course, there are very few such questions, and the vast majority of questions are the comparative size of different denominator scores.

Fractional comparison.

In fact, there is a crude method, and it is omnipotent, but it is faster for some questions, and sometimes the amount of calculation is larger.

According to the relationship between fractions and division, fractions are equivalent to the quotient of division equations. Therefore, comparing the size of fractions can reduce fractions to decimals.

I believe everyone knows that the size of the decimal is compared, starting from the highest digit until the digits of the size are separated. Sometimes, the size of the two fractions can be derived directly from the estimate. For example, 2 3 and 3 4 compare the size, the former is about how many decimals, the latter is a few, who is big and who is small, at a glance.

Molecules. Some netizens may find this statement a bit strange. Is there such a thing as a generalist? In fact, it is also very simple, and it is similar to the denominator. Because the numerator is equivalent to the dividend.

It is fixed that the smaller the divisor, the larger the quotient, and the larger the divisor, the smaller the quotient obtained.

Pass value. If the difference between the numerator and the denominator of the two fractions is the same, then the greater the sum of the numerator and denominator, the greater the fraction. The other way around, the smaller.

If the difference is different, we can use the numerator and denominator to make their difference the same, so that it is much easier to compare.

DenominatorThe bigger the score, the smaller the score, and the larger the numerator, the bigger the score, which is learned in the fifth grade.

A fraction indicates that a number is a fraction of another number, or the ratio of one event to all events. The unit "1" is divided into several parts, and the number of such parts or parts is called a fraction. The numerator is on top and the denominator is on the bottom.

When the denominator is 100 in the special case, it can be written as a percentage.

form, such as 1%.

A fraction can be expressed as a division equation: for example, one half is equal to 1 divided by 2. where 1 numerator is equal to the dividend, the fractional line is equal to the divisor, the 2 denominator is equal to the divisor, and the fractional value is equal to the quotient.

Nature of Fractions:

A fraction is either a finite decimal or an infinite cyclic decimal, and an infinite non-cyclic decimal like etc. cannot be replaced by a fraction.

Another property of fractions is that when the numerator and denominator are multiplied or divided by the same number at the same time (except 0), the fractional value does not change. Therefore, for each score there is an infinite number of equal scores. Taking advantage of this property, it is possible to divide and divide.

A power operation on a fraction cannot result in an integer, and if the fraction before the operation is the simplest, the result will also be the simplest.

The larger the numerator of the fraction, the greater the value of the fraction is incorrect. Because there is only a denominator.

At the same time, the larger the fraction, the greater the fraction. If this premise is missing, the key spine is not right. For example, five-fourths and four-twoths, the numerator of the previous fraction is larger, but the fractional value is indeed the second larger.

A fraction is a part of a whole, or more generally, any part of a number of manuscripts that bleed equally. It is expressed as a ratio of an integer a to an integer b (a is a false fraction of a multiple of b.

Whether or not it is a score is debatable).

A fraction represents a fraction of a number that is another number, or the ratio of an event to all events in a high poly. The unit "1" is divided into several parts, and the number of such parts or parts is called a fraction. The numerator is on top and the denominator is on the bottom.

When the denominator is 100 in the special case, it can be written as a percentage.

form, such as 1%.

The denominator is the same, and the larger the numerator, the larger the fraction. The numerator is the same, and the smaller the denominator, the larger the fraction.

The numerator and the denominator are multiplied or divided by a number of the same denominator at the same time (except 0), and the magnitude of the fraction does not change, which is the basic property of the fraction.

The numerator is on top and the denominator is below, and it can also be regarded as division, dividing the numerator by the denominator (because 0 cannot be a divisor in division, so the denominator cannot be 0), and vice versa, division can also be expressed as a fraction.

Right. The smaller the numerator with the same denominator, the larger the fraction.

When comparing the size of the same numerator fraction, the higher the denominator, the larger the fraction. This statement is false.

The analysis process is as follows:

When comparing the size of the same numerator fraction, the larger the denominator, the smaller the fraction.

For example, 1 2 and 1 3 compare the size, because the numerator is 1 and the denominator is different, so you need to pass the division first and then compare the size.

1 2-way divided into: 3 6.

1 3-way divided into: 2 6.

3 6 2 6, so 1 2 1 3.

The denominator is the same, the smaller the numerator, the smaller the fraction; The numerator is the same, and the larger the denominator, the smaller the fraction.

No, if it's a negative number, the higher the denominator, the bigger the fraction.

The numerator is the same, and the larger the denominator, the smaller the fraction.

Wrong. When the denominator of a fraction is the same, the larger the numerator, the larger that fraction will be; If this score is not positive, if it is negative, the result is reversed. Fractions represent a part of the whole, or more generally, any equal number of parts.

The denominator must not be 0 because the denominator is equivalent to the divisor. Otherwise, the equation cannot be held and the numerator can be equal to 0 because the numerator is equivalent to the dividend. It is equivalent to 0 divided by any number, regardless of the denominator, the answer is 0.

The numerator or denominator in a fraction cannot be an irrational number (such as the square root of 2) after being reduced, otherwise it is not a fraction.

Only two prime factors, 2 and 5, can be reduced to finite decimal numbers in the denominator of a simplest fraction; If the denominator of the simplest fraction contains only prime factors other than 2 and 5, then it can be reduced to a pure cyclic decimal; If the denominator of the simplest sail fraction contains both prime factors of 2 or 5, as well as prime factors other than 2 and 5, then it can be reduced to a mixed cyclic decimal. (Note: If it is not the simplest score, it must be turned into the shortest score first, and then judged by hail; The simplest fraction with a denominator of 2 or 5 must be reduced to a finite decimal, and the simplest fraction of another prime with a denominator must be reduced to a pure cyclic decimal).

Summary. 2 2 is 1 approximate fraction, and 2 2 can be regarded as a false fraction, so it is also okay to compare.

You can use 2 8< 2 3 or 2 8< 2 5.

The numerator is the same, and the smaller the denominator, the larger the fraction, right?

What if 2/8 and 2/2.

2 8< 2 2, you can also.

But 2/2 is 1 can be compared? According to the title.

2 2 is 1 approximate fraction, and 2 2 can be regarded as a false fraction, so it is also okay to compare. You can use 2 8< 2 3 or 2 8< 2 5.
