The method
Divide the numerator by the denominator to get a decimal, then multiply by 100. “Per cent” means per hundred, so the multiplication is a change of unit, not a change of value.
5 ÷ 8 = 0.625 → 0.625 × 100 = 62.5%
The shortcut worth knowing
When the denominator divides into 100 cleanly, scale directly: 3/25 becomes 12/100 by multiplying both terms by 4, so 12%. This is faster than dividing and is how the common fractions are usually memorised.
| Fraction | Decimal | Percent |
|---|---|---|
| 1/2 | 0.5 | 50% |
| 1/3 | 0.333… | 33.3% |
| 1/4 | 0.25 | 25% |
| 1/5 | 0.2 | 20% |
| 1/8 | 0.125 | 12.5% |
| 2/3 | 0.666… | 66.7% |
| 3/4 | 0.75 | 75% |
| 5/8 | 0.625 | 62.5% |
Improper fractions exceed 100%
That is correct, not an error. 5/4 is 125%. Percentages above 100 are fine whenever the quantity can exceed the reference — growth, marks with bonus credit, recovery rates.
