## How to Convert Decimal Numbers to Percent

Conversions of decimals, fractions, and percent is a very important basic skill in mathematics and many problems in the Civil Exams require this skill. Being able to convert from one form to another will help you speed up in calculations.   For example, instead of multiplying a number by 25%, you just have to get its 1/4 or simply divide it by 4.

Percent usually appears in discount and interest problems while fractions and decimals appear in various types of problems.
