Why Do We Use Percentages?

Percentages are a common way to express fractions and ratios in everyday life. They are particularly useful when comparing two quantities of different sizes. For example, if you want to compare the number of men and women in a group, it’s much easier to express the ratio as a percentage (e.g. 40% men and 60% women) than as a fraction or decimal.

How to Convert a Percentage to a Decimal

Converting a percentage to a decimal is also quite simple. To convert a percentage to a decimal, simply divide the percentage by 100. For example:

20% = 20/100 = 0.2

50% = 50/100 = 0.5

75% = 75/100 = 0.75

How to Convert a Decimal to a Percentage

Converting a decimal to a percentage is just as easy. To convert a decimal to a percentage, simply multiply the decimal by 100. For example:

0.2 = 0.2 x 100 = 20%

0.5 = 0.5 x 100 = 50%

0.75 = 0.75 x 100 = 75%
