Step by step
The question
Question: work out 75% of 64.
75% of 64
1 Percent
Percent means out of 100.
So 75% is 75/100.
= 75100 × 64
Both 75 and 100 can be divided by 25.
That makes it simpler.
= 75 ÷ 25100 ÷ 25 × 64
So it is 3/4.
= 34 × 64
2 Times and divide
"Of" means times.
of = ×
Before we multiply, we make the numbers smaller.
64 on top and 4 at the bottom both divide by 4.
A top and a bottom divided by the same number: the answer stays the same.
64 and 4: ÷ 4 → 16 and 1
So we multiply smaller numbers.
= 31 × 161
3 times 16 is 48.
= 48
So the answer is 48.
Let's look back.
First: percent.
Last: times and divide.
Answer
= 48
