Three ways to work it out

All three give the same answer — pick whichever is easiest to do in your head for these numbers.

Method	Working	Result
Decimal	500 × 0.18	90
Divide by 100 first	(500 ÷ 100) × 18 = 5 × 18	90
Ten-percent chunks	10% of 500 = 50, then × 1.8	90

Nearby percentages of 500

Handy when you are comparing a tip, a discount, or a tax rate rather than one fixed figure.

Percent	of 500	500 minus it
5%	25	475
10%	50	450
15%	75	425
18%	90	410
20%	100	400
25%	125	375
50%	250	250

The last column is what is left after taking that percentage off — the number you actually pay after a discount, or keep after a deduction.

The reverse question

Going the other way — 90 is what percent of 500? — divides instead of multiplying: (90 ÷ 500) × 100 = 18%. That is the form to use when you know the part and the whole but not the rate, such as working out a score as a percentage or how much a price moved.

And to find the whole from the part: if 90 is 18% of some number, that number is 90 ÷ 0.18 = 500.
