How to read it
- Percent means hundredths. 15% is 0.15, so multiplying the base by 0.15 gives the answer.
- A discount subtracts, tax or tip adds. For the same 15%, the gap between the two results is twice the value.
- "What percent" is a division: 15 ÷ 200 × 100. When it does not come out even, the figure shown is rounded.
