Percentage Practice

Tips for faster percentages

Includes multiple modes: P% of N, find the percent, and find the total.

• Find the part: 15% of 80 = 10% of 80 + 5% of 80 = 8 + 4 = 12.
• For 1%: divide by 100, then scale up.
• Find the percentage: 12 is what percent of 80? (12 ÷ 80) × 100 = 15%.
• Find the whole: 12 is 15% of what number? 12 ÷ 0.15 = 80.
• Common mistake: moving the decimal the wrong direction.
• Common mistake: confusing part vs whole in word-style percent questions.
• Prefer clean numbers first (multiples of 10) then increase difficulty.
• Try mixed-mode practice once each mode is comfortable.
