Question

Как из десятичной дроби получить обыкновенную дробь? Как из обыкновенной поучить десятичную? Например 0,4; 0,95

Answer 1

Допустим, дробь 1/5
Приводишь к числу 10, 100, 1000 и т.д.
1/5=20/100
далее пишешь: 0,20
0,4=40/100
0,95=95/100

Answer 2

0, 4 = 4    2
         --- =---
         10   5

0,95 = 95        19
          -----  =  -----
           100      20

4        
---  = 0,2     то есть знаменатель и числитель умножаем на такое число 
20
 чтобы в знаменателе получилось или 10 или 100 или 1000 и т. д.

Converting Decimal to Fraction:

To convert a decimal to a fraction, you can follow these steps:

1. Identify the Place Value: - Identify the place value of the last digit after the decimal point. This will determine the denominator of the fraction.

2. Write the Decimal as a Fraction: - Write the decimal as a fraction with the identified place value as the denominator and the digits before the decimal point as the numerator.

3. Simplify the Fraction: - If possible, simplify the fraction by finding the greatest common divisor of the numerator and denominator and dividing both by it.

For example, to convert 0.4 to a fraction: 1. The place value of 4 is tenths. 2. Writing 0.4 as a fraction gives us 4/10. 3. Simplifying 4/10 gives us 2/5.

This process can be applied to other decimal numbers as well.

Converting Fraction to Decimal:

To convert a fraction to a decimal, you can use division to find the decimal equivalent.

1. Perform Division: - Divide the numerator by the denominator.

2. Round the Decimal: - If the division does not result in a terminating decimal, round the decimal to a certain number of decimal places.

For example, to convert 95/100 to a decimal: 1. Performing the division 95 ÷ 100 gives us 0.95.

This method can be used for any fraction to convert it into a decimal.
