The question

Question: work out 150% of 40.

150% of 40

1 Percent

Percent means out of 100.

So 150% is 150/100.

= 150100 × 40

Both 150 and 100 can be divided by 50.

That makes it simpler.

= 150 ÷ 50100 ÷ 50 × 40

So it is 3/2.

= 32 × 40

2 Times and divide

"Of" means times.

of = ×

Before we multiply, we make the numbers smaller.

40 on top and 2 at the bottom both divide by 2.

A top and a bottom divided by the same number: the answer stays the same.

40 and 2: ÷ 2 → 20 and 1

So we multiply smaller numbers.

= 31 × 201

3 times 20 is 60.

= 60

So the answer is 60.

Let's look back.

First: percent.

Last: times and divide.

Answer
= 60
