Step by step
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
