Question

Fill in the missing number.
70% of _____=42

Answer 1

60

Explanation:

70% of x = 42

.7x = 42

x = 42 ÷ .7

x = 60

Answer 2

60

Explanation:

We have, 70% × x = 42

or,

`(70)/(100)` × x = 42

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

we have x = 42 ×
`(100)/(70)`

x = 60

If you are using a calculator, simply enter 42×100÷70, which will give you the answer of 60
