Finding the percentage of a percentage involves converting both to decimal form by dividing by 100 and then multiplying them together. Use the following formula:

_{1}÷ 100) × (pct

_{2}÷ 100) × 100

Start by dividing each percentage by 100 to convert them to a decimal form. Then multiply the decimals together to get the result. Multiply the result by 100 to get the final percentage.

**Example: Find 25% of 80%**

p = (pct_{1} ÷ 100) × (pct_{2} ÷ 100) × 100

p = (25 ÷ 100) × (80 ÷ 100) × 100

p = .25 × .8 × 100

p = .2 × 100

p = 20%
