The big ideaA percent is a number out of 100. One percent is one hundredth of the whole.

How it works

A percent is a number out of 100. One percent is one hundredth of the whole.

To find a percent of a number, find 1% (divide by 100) and multiply, or use tens.

75% of 300 is 225.

3/4 is shaded
75% is 75 out of 100.

Example 1: A percent of stickers

  1. Mia has 300 stickers and 75 percent are moons.
  2. 10% of 300 is 30, so 70% is 210. 5% is 15.
  3. 75% of 300 is 225.

Example 2: A percent of cards

  1. Leo has 240 cards and 90 percent are foil.
  2. 10% of 240 is 24, so 90% is 24 × 9 = 216.
  3. 216 cards are foil.

Example 3: A percent of money

  1. Ava has 30 dollars and spends 63 percent.
  2. 1% of 30 is 0.30, and 63 × 0.30 = 18.90.
  3. She spends 18.90 dollars.
