1Per cent means out of 100

A percentage is a fraction with a denominator of 100.

Example

42 out of 100 = 42100 = 42%

2Benchmarks to know

  • 50% = 12 = 0,5
  • 25% = 14 = 0,25
  • 10% = 110 = 0,1
  • 1% = 1100 = 0,01

3Fractions to percentages

Make an equivalent fraction with a denominator of 100.

Example

1120 = 55100 = 55%
14 out of 25 = 56100 = 56%

4Decimals and percentages

Decimal to percentage: multiply by 100. Percentage to decimal: divide by 100.

Example

0,78 × 100 = 78%
34% ÷ 100 = 0,34

5Percentage of a number

  • Find 10% by dividing by 10, or 1% by dividing by 100.
  • Build up: 5% is half of 10%. 25% is a quarter.
Example

10% of 420 = 42
40% of 420 = 4 × 42 = 168
25% of 88 = 88 ÷ 4 = 22

6Discounts

Find the discount first. Then subtract it from the price.

Example

20% off R150:
10% of 150 = 15 and 20% of 150 = 30
150 − 30 = R120
