Problem description: What are the basic properties of fractions based on the basis of fractions? () True or false.

Analysis: Right.

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

<> fraction indicates that a number is a fraction of another number and is expressed as the ratio of an integer a to an integer b. Its properties are:

1. Fractions can be expressed as a division equation. For example: half equals 1 divided by 2.

2. Fractions can also be expressed as a ratio. For example, one half is equal to 1 to 2.

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

4. The numerator and denominator of the fraction are multiplied or divided by 0 at the same time, except for the same number, and the fractional value will not change.

5. The result of the power operation of the fraction cannot be an integer, and if the fraction before the operation is the simplest, the result will also be the simplest. For example, two-thirds squared equals four-nineths.

The basic properties of fractions: the numerator and the denominator expand at the same time and the latter shrink by the same multiple, and the fractional value remains unchanged.

The basic nature of decimals: 0 is added to the end of the decimal and 0 is removed, and the size of the decimal remains the same

Their basic nature should be that their size will not change

One-half, three-sixth, nine-eighteenth.

One-half, two-quarters, four-eighths.

The basic property of a fraction: the numerator and denominator of a fraction expand or shrink by the same multiple (except 0) at the same time, and the fractional value remains the same.

The basic properties of decimals: add 0 to the end of the decimal or remove 0, and the size of the decimal remains the same.

The basic property of fractions is that the numerator or denominator of a fraction is multiplied or divided by a number that is not equal to 0 at the same time, and the fractional value does not change.

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

The basic property of a fraction is that the numerator or denominator of a fraction is multiplied or divided by the same number at the same time, except that the fraction size does not change.

5th Grade Math Problems - Basic Properties of Fractions.

1.Multiply or divide the numerator and denominator of the fraction by the same number (except 0) at the same time, and the unit of the fraction remains the same. ......

Because: the unit of fraction is variable, such as three-quarters, multiplied by 7 at the same time, it becomes twenty-one twenty-eighths, and the unit of fraction changes.

57 out of 76 is the ......... simplest fraction

Because: 76 57 still has 19 common factors, and you can continue to reduce it.

2.A fraction, the numerator is 1 after adding 1 and subtracting 2 is 3/4, what is this fraction?

A: Yes 11/12.

3/4 of the numerator and denominator multiplied by 3 equals 9/12, plus 3 equals 11/12, and 11/12 plus 1 equals 1/12, which can be divided into approximately 1

3.A fraction, the numerator plus 1, has a value of 3/4; After subtracting 1 from the numerator, its value is 1/2, find this fraction?

A: Yes 5 out of 8.

3/4 of the numerator and denominator multiplied by 2 at the same time equals 6/8 and can be divided into about 3/4; Minus 1 is equal to 5/8, and 5/8 minus 1 is equal to 4/8, which can be divided into about 1/2.

The fraction is in fact equal to a variation of division, e.g. 4 divided by 5 can be expressed as 4 5

So numerator = denominator * fractional value (quotient) or denominator = numerator fractional value (quotient) fractional value (quotient) = numerator denominator. Solution:

32 If the numerator is 1, then divide the numerator and denominator by 8 to get 1 4

3 5 The denominator should be 25, and the numerator and denominator should be multiplied by 5 to get 15 25

7 9 The numerator should be 56 and the denominator should be multiplied by 8 to get 56 72;

3. The addition or subtraction of the numerator and denominator with the same number cannot guarantee that the fractional value will not change, so.

7 8 The numerator plus 14 is 21 is three times that of 7, and the numerator and denominator are multiplied by 3 to denominator 24 that is added (16).

In the same way, 36 48 denominator minus 34 is 14, which is equal to 48 times 7 24 times, then the numerator and denominator are multiplied by 7 24, and the numerator is 36 times 7 24 = 21 2 36-21 2 = 51 2 (there is no need to write the form with fractions here), that is, the numerator should be subtracted (51 2);

12 18 The numerator minus 6 becomes 6 equals the numerator divided by 2 Therefore, to remain the same, the numerator denominator should be divided by 2 The denominator should be divided by (2). Finished.

16;There is a problem with this question, it should be subtracted from 24 instead of 34; 2

Fractions: Put units"1"Dividing it into several portions equally, representing such a portion or portions, is called a fraction.

The basic property of fractions: the numerator and denominator of fractions are multiplied or divided by the same number at the same time (except 0), and the magnitude of the fraction does not change. The property of quotient invariance: the dividend and the divisor expand or decrease by the same multiple at the same time, and the quotient does not change.

Reduction: Reducing a fraction into a fraction that is equal to him, but the numerator and denominator are relatively small, is called a fraction.

General score: The different denominator fractions are divided into fractions with the same denominator that are equal to the original fractions, which is called universal fractions.

The numerator and denominator of the fraction are multiplied or divided by the same number at the same time (except 0), and the magnitude of the fraction remains the same.

You're talking about the numerator plus 6.

Hehe, in fact, the fraction and the proportion are about the same.

If the numerator is added to 6, it is equivalent to the numerator increasing the original 6 13, so the denominator should also be added to the original 6 13

So the denominator should be added 18 13

Let the denominator add x

13+6）/（3+x）=13/3

x=18/13

So the denominator is added 18 13

It should be a numerator plus 6, a fraction plus 6, how has it changed.
