Percentages are perhaps the most common way to express a number that is part of a whole. You will see percentages used in everyday places like banks and supermarkets. Decimals and fractions express a number that is part of a whole, so you can easily change either into an equivalent percentage.

## From Decimal to Percentage

Find the equivalent percentage to a decimal number by multiplying the decimal by 100 and adding a percent symbol. When you multiply a decimal by 100, move the decimal point two places to the right. Consider the decimal 0.831 as an example:

0.831 x 100 = 83.1%

## From Fraction to Percentage

Converting a fraction to a percentage is the same as converting a decimal, but with one extra step. Divide the top number of the fraction by the bottom number. The result will be a decimal that you can then multiply by 100 and add a percent symbol to. Consider the fraction 1/4 as an example:

1/4 = 0.25, so 0.25 x 100 = 25%
