Cheat Sheet
- Converting Between Fractions, Decimals, and Percentages -
Remember that "percent" means "per hundred," so move the decimal two places right to convert a decimal to a percent (e.g., 0.75 → 75%). To go from a percent to a decimal, divide by 100 (e.g., 45% → 0.45). This method is endorsed by Cambridge University's mathematics curriculum for clarity and speed.
- Calculating a Part of a Whole -
Use the formula part = (percent/100) × whole to find amounts quickly; for example, 20% of 150 is 0.20 × 150 = 30. This fundamental approach is taught in Khan Academy resources and helps solve real-world percentage questions, like tax or tip calculations. Practice with varied numbers to build confidence in setting up the equation.
- Determining Percentage Increase and Decrease -
Apply (new - original) ÷ original × 100 to find percent change: moving from 80 to 100 is (100 - 80) ÷ 80 × 100 = 25% increase. This formula is widely used in financial reports and economic studies for tracking growth or decline. A neat mnemonic - "Difference over old, times a hundred" - keeps the steps straight.
- Reversing Percentage Problems -
When you know the result after a percent change and need the original, divide by the growth factor: original = result ÷ (1 ± percent/100). For instance, if $80 is after a 20% discount, compute 80 ÷ 0.80 = $100. This reverse strategy is highlighted in many university-level business math courses.
- Handling Successive Percentage Changes -
For back-to-back changes, multiply factors rather than adding percentages: two successive 10% increases yield 1.10 × 1.10 = 1.21 (a 21% net increase). The compound factor method, recommended by financial textbooks like those from the American Mathematical Society, avoids common pitfalls. Visualize each step as a new baseline to stay organized.
