The question
Question: work out 25% of 80.
25% of 80 = ?
Percent means out of 100.
So 100% is all of it.
25% is a part we get by halving.
100% = all of it
1 Start with all
100% of 80 is all of it: 80.
100% of 80 = 80
2 Halve
50% is half of 100%.
Half of 80 is 40.
50% of 80 = 80 ÷ 2 = 40
25% is half of 50%.
Half of 40 is 20.
25% of 80 = 40 ÷ 2 = 20
So 25% of 80 is 20.
25% of 80 = 20
Let's look back.
First: start with all.
Last: halve.
Answer
25% of 80 = 20
