Numbers can be expressed in fractions as well as in decimals. First let us know the definitions of both.
A decimal number is a number which has a dot(.) or decimal point between the digits. Basically, decimals are nothing but the fractions with denominator as 10 or multiples of 10.
Example: 5.7, 8.5, 11.98 etc.
Fraction is a part of a whole number. It is denoted as a ratio of two numbers a/b, where a and b are integers, also b≠0. The two numbers are called the numerator and denominator.
Example: 3/4, 5/8, 9/4 etc.
Conversion of decimal into fraction
To convert decimal into fraction we follow the given steps
- Firstly, count the numbers after the decimal point or right side of the decimal point.
- If n is the number of digits on the right side of the decimal point, then multiply and divide the whole number by 10n to remove the decimal from the numerator.
- After that, you can simplify the number, by reducing the numerator and denominator.
- The resultant will be the required fraction from the given decimal number.
