The question
Question: work out 12.5% of 40.
12.5% of 40 = ?
Percent means out of 100.
So 100% is all of it.
12.5% is a part we get by halving.
100% = all of it
1 Start with all
100% of 40 is all of it: 40.
100% of 40 = 40
2 Halve
50% is half of 100%.
Half of 40 is 20.
50% of 40 = 40 ÷ 2 = 20
25% is half of 50%.
Half of 20 is 10.
25% of 40 = 20 ÷ 2 = 10
12.5% is half of 25%.
Half of 10 is 5.
12.5% of 40 = 10 ÷ 2 = 5
So 12.5% of 40 is 5.
12.5% of 40 = 5
Let's look back.
First: start with all.
Last: halve.
Answer
12.5% of 40 = 5
