CONVERTING DECIMAL TO FRACTION
Example:
1. Make 12.2 into a whole number.
In this case, multiply 12.2 by 10.
2. Whatever is multiplied to 12.2 should also be divided to it so as not to change the value of 12.2.
Therefore:
12.2 * 10/10 = 122/10 or 61/5 in fraction in lowest term
Just divide the numerator by the denominator. You get the decimal value.
For e.g. 1/2 = .5
1/4 = .25
.
0.85

A decimal number is not an integer. An integer is a number that is not a fraction, and decimal numbers are decimal fractions.
The relationship between fractions and decimals can be seen as follow. Fractions can be represented as ratio of two numbers and on dividing can give a decimal value. And decimal value can be converted into a fraction too.

Fractions in decimal form are easy to compare and to add and subtract from one another.
A percentage is a special way of writing fractions with a denominator of 100. For example, 33% = 0.33 or 33/100.A decimal is also a special way of writing fractions - with a denominator that is a power of 10. Which power, depends on the number of decimal digis. For example, 0.125 = 125/1000.
243 hundredths in decimal fractions = 2.43
