How we explain it

Children can open this short lesson before they practice.

  1. Percent means out of 100.
  2. Find 10% by dividing by 10. Find 1% by dividing by 100.
  3. For a discount, find the percent of the price, then subtract it.

Example: A $40 shirt is 25% off. What is the sale price? 25% is one quarter: $40 ÷ 4 = $10 off. $40 − $10 = $30. Answer: $30
