How to work it out
- Turn the percentage into a decimal: 5 ÷ 100 = 0.05
- Divide the part by it: 30 ÷ 0.05 = 600
- Check: Work forwards: 5% of 600 is 0.05 × 600 = 30.
Another method. As a proportion: 30/whole = 5/100, so whole = 30 × 100 ÷ 5 = 600. Both methods always give the same answer.
In a spreadsheet: =30/5%. Multiplying the part by the percentage instead of dividing gives a smaller number. The whole must be bigger than the part whenever the percentage is below 100.
What the result means
30 is the 5% share of 600. The other 95% is 570.
Discounts: if 30 dollars is a 5% saving, the original price was $600.
Using 1% as a stepping stone
If 5% is 30, then 1% is 30 ÷ 5 = 6, and any other percentage follows: 10% is 60, 50% is 300 and 100% is 600.
