Question

There were 28 children in the final of the Air Guitar competition. If 25% of the finalists were girls, who
many boys were there in the final?

Answer 1

Answer: 21 of the finalists were boys.
Explanation:
We are trying to figure out what 25% of 28 is. We can convert 25% into a fraction.
25%= 1/4 and 28= 28/1
Multiply and you’ll get: 28/4 which equals 7.
So 25% of 28 is 7.
With the remaining step, you subtract 7 from 28 to get the amount of boys in the final because 7 is the amount of girls.
28 finalists- 7 girls = 21 boys
