answer: 21 is 70% of 30

Working out percentages

We have, 70% × x = 21 or,  70100  × x = 21

Multiplying both sides by 100 and dividing both sides by 70,

we have x = 21 ×  100 70 x = 30

If you are using a calculator, simply enter 21×100÷70, which will give you the answer.

number of cars = [tex]\frac{21}{70}[/tex] × 100 = 30
