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:

p = (pct1 ÷ 100) × (pct2 ÷ 100) × 100

p = (pct1 ÷ 100) × (pct2 ÷ 100) × 100
p = (25 ÷ 100) × (80 ÷ 100) × 100
p = .25 × .8 × 100
p = .2 × 100
