What percent is 8.62 of 35.90?
x/100 = 8.62/35.90
Cross multiplication:
(8.62 * 100) / 35.90
≈ 24%
An easy way to remember how to solve this type of problems is to write them as a proportion and then cross multiply.

The percentage
= (8.62/35.9) × 100%
= 24.0% (3 sig. fig.)
= (8.62/35.9) × 100%
= 24.0% (3 sig. fig.)

8.62/(35.90 - 8.62) = K.
plug & play
