💯 How Do You Find a Percent?
6th Grade ➗ Math
A percent is a part out of 100. "20 percent" means 20 out of every 100.
What "percent" means
The word percent comes from Latin per centum — "for each hundred." So 50% is 50 out of 100, which is the same as one half, and 25% is one quarter.
Finding a percent of a number
To find 20% of 50, change the percent to a decimal (20% = 0.20) and multiply: 0.20 × 50 = 10. Another way: divide by 100 to find 1%, then multiply. 50 ÷ 100 = 0.5, and 0.5 × 20 = 10.
What percent is it?
To find what percent one number is of another, divide the part by the whole and multiply by 100. 10 out of 50 is 10 ÷ 50 × 100 = 20%.
Percents in real life
Stores use percents for sales ("30% off"), weather apps use them for the chance of rain, and your test score is often a percent too.
