How to work it out
- Turn the percentage into a decimal: 30 ÷ 100 = 0.3
- Multiply: 0.3 × 79 = 23.7
- Check: Work backwards: 23.7 ÷ 79 × 100 = 30%.
Another method. As a proportion of part to whole: 30/100 = part/79, so part = 30 × 79 ÷ 100 = 23.7. Both methods always give the same answer.
In a spreadsheet: =30%*79. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.
What the result means
23.7 is the 30% share of 79. The remaining 70% is 55.3, and the two parts add back up to 79.

Adding and taking away 30%
Increasing 79 by 30% gives 102.7 and decreasing it by 30% gives 55.3. These do not cancel out: raising 79 by 30% and then lowering the result by 30% ends at 71.89, because the second 30% is taken of a bigger number.
