How do I convert a band fraction to a decimal place? How do you turn a fraction into a decimal place

Divide the denominator of the fraction by the numerator of the fraction and you're good to go. If there is an integer in front of it, add the integer in front of it, and the conversion is successful.

For example: 1 and 3/5 = 1+3 5=1+;

4 and 2/5 = 4+5 2 = 4+.

Method of converting fractions to decimals:

1. The integer part of a decimal is the same as the integer part with a fraction.

2. Add a decimal point after the integer part of the decimal number.

3. Divide the numerator of the fractional part with the fraction by the denominator, and write the resulting decimal after the decimal part.

4. According to the requirement of retaining decimal places in the question, the number of decimal places is determined by rounding.

For example, if 2 and 1 2 are converted into decimals, first extract the 2 in front of the fraction and write it separately. Then calculate the decimal of the following fraction, i.e. 1 2 = 1 2 =. That is, 2 and 1 2 are decimalized.

With scores. Decimal: The numerator is the number next to the fraction denominator.

The numerator, the denominator does not change.

Another 7/100

The numerator is 1x100 + 7 = 107, and the denominator is unchanged at 100, so 1 and 7/100 = 107/100

Another 9/20

The numerator is 2x20+9=49, and the denominator is unchanged is 20, so 2 and 9/20 = 49/20

Another 7/16

The numerator is 7x16+7=112, and the denominator is unchanged at 16, so 7 and 7/16 = 112/16

One hundred and seven is equal to one hundred hundred and seven.

Dividing 107 by 100 equals.

That's 107%.

Algebra multiplies by the denominator plus the numerator as the numerator and the denominator does not change.

Divide the decimal denominator by the numerator and add the integer part.

Use the numerator of the denominator of the fraction and add the integer next to it.

is to divide the numerator of the fraction by the denominator, and then add the preceding integer.

Divide the denominator of the fraction by the numerator.

Divide the numerator by the denominator and add the integer part.

The part of an integer with a fraction x denominator is the numerator of the molecule.

The denominator remains the same.

The numerator is divided by the denominator. The numerator is the dividend, the denominator is the divisor, and then the division can be exhausted, and the inexhaustible can be retained with a few decimal places.

Fractional decimal can be divided into three cases:

1.Fractions are reduced to finite decimals. A sufficient requirement for a simplest fraction to be reduced to a finite decimal is that the prime factors of the denominator are only 2 and 5.

2.Fractions are reduced to pure cyclic decimals. A sufficient and necessary condition for a minimum fraction to be reduced to a pure cyclic decimal is that there are no 2s and 5s in the prime factor of the denominator, and that the number of digits of the cyclic section is equal to the number of 9 in the smallest number of 999 that is divisible by the denominator of the simplest fraction.

3.Fractions are reduced to mixed loop decimals. A simple fraction is sufficiently necessary for it to be converted into a mixed cyclic decimal if the denominator contains both prime factors of 2 or 5 and prime factors other than 2 and 5.

In the formed mixed cyclic decimals, the number of non-cyclic digits is equal to the greater of the exponents of factor 2 or 5 in the denominator; The number of digits of the cyclic section is equal to the number of the smallest number of 999 that can be divisible by a factor different from 2 and 5 in the denominator, and the number of 9.

The way to turn the score into a small stupid trembling number:

1. First, the fraction with the fraction is turned into a false fraction, and the denominator + numerator of the integer part with the fraction is unified into the numerator of the false fraction, and the parents of the original fraction are still the parents of the false fraction.

For example: 2 and 3 5, the numerator of the false fraction is 2*5+3=13, the denominator is 5, and the false fraction is 13 5.

2. The numerator and denominator of the false division with the number of ants is the decimal number.

For example: 13 5, 13 5=

The integer part of the year remains the same, do the decimal point integer part, the decimal part knows Lao Tzu divided by the denominator, and the inexhaustible ones are kept by asking for a few decimals.

Take the integer part with a fraction as the integer part of the decimal and divide the numerator of the fractional part with a fraction by the quotient of the denominator as the decimal part.

The integer part with a fraction is the integer part of the decimal (the part before the decimal point).

The true fraction part with the fraction is divided by the denominator, and the obtained quotient (less than 1) is made as the small comma part (the part after the decimal point is grinded).

First, the band fraction is converted into a true fraction, and finally the numerator is divided by the denominator to calculate the decimal.

The numerator in the fraction is less than the denominator, if you want to turn it into a decimal, the integer does not change, you only need to ask for the result of the fraction, plus the integer is the result of the fraction

The true fraction is divided by the numerator by the denominator, and the resulting decimal is combined with the integer part.

The decimal is divided into fractions, first of all, the number before the decimal point remains unchanged, and the remaining decimal part can be converted into fractions according to the method of decimal fractions.

Decimals whose integer parts are not zero can be reduced to fractions. The integer part is an integer with a fraction, and the decimal part is a few decimal places, one decimal place means tenths, two decimal places represent hundredths, and three decimal places represent thousandths.

Such as 7 10

Again 21 100

and 327 1000

Fraction: The numerator is the number next to the fraction and the denominator + numerator.

The denominator is unbalanced.

For example: 2 and 3 4

The numerator is 2 4 + 3 = 11, and the denominator is unchanged 4

So 2 and 3 4 = 11 4

Rechemical fiber rock barrier into decimal: 11 4 = 11 4 =

With fractions to serve decimals:

1. The integer part of the old Jingfeng number with points remains unchanged;

2. Partially divide the true fraction with fraction into decimal places (numerator divided by denominator);

3. Merge the two parts.

For example, 2 and 1/4 are decimalized.

The integer part 2 remains unchanged.

1/4 = 1 4=

2 and 1/4 =

The numerator is the number denominator + numerator next to the fraction, and the denominator does not change. To calculate addition and subtraction with fractions, you need to add and subtract the integer part and the fraction part separately. If the fraction of the subtracted fraction is less than the fraction of the subtraction, you need to take 1 from the integer part of the subtracted fraction and turn it into a false fraction, and then subtract it with the fraction of the original subtracted fraction.

When calculating multiplication and division, it is necessary to convert it into a false fraction.

Introduction with fractionsA band fraction is a form of false fraction. The fraction (or the number after the addition and subtraction of the true fraction and the false fraction) of a non-zero natural number and the true fraction (or the addition and subtraction of the true fraction and the false fraction) is generally read as a few and a few fractions, and the reciprocal of the false fraction must not be much more than one.

Fractional pseudofraction: The denominator remains unchanged, and the numerator is the product of the integer part multiplied by the denominator plus the sum of the original numerator.

To convert a false fraction into an integer or a fraction, divide the numerator by the denominator: if it is divisible, the resulting quotient is an integer; If it is not divisible, the quotient is the integer part with the fraction, and the remainder is the numerator of the fraction that defeats the mu part, and the denominator remains unchanged.

First of all, the decimal must be greater than 1 in order to achieve the score of pure tung shenghua.

The integer part of the decimal does not change, and there are several decimal places in the decimal part, one denominator is 10, and the two denominator is 100. The numerator is the fraction of the wheel, and then the fraction can be simplified.

For example: 2 100 = 1 and 1 50

Ding Hanrui: "How do decimals become fractions? First of all, the single digit remains the same, there are a few decimal places, there is one is a few tenths, two is a few hundredths, three is a few thousandths, for example, look at the decimal point first, 5, is 5 10 (note, can not be played, here read ten strikes and rolls of five), find the greatest common factor of 5 and 10, the maximum common factor is 5, 5 5 = 1, 10 5 = 2, 1 2 (beat more than one-half) and the single digit does not change, that is, 2 and 1 2 (two and one-half).

Examples. One hundred and thirty-six).

The greatest common factor of 36 and 100 is 4

36 4 = 9, 100 4 = 25, that is, 9 25 (nine-fifths of twenty-fifths) add the 3 in the single place, that is, 3 and 9 25 (three and nine-fifths).

The maximum number of common cause pins in the example problem is 25).

5 and 3 4 have you learned in front of the screen
