Question

Four fifths of the children in a school are boys. Five eighths of the girls in the school are right-handed. What fraction of the children in the school are left-handed girls?

Answer 1

See below

Explanation:

Let x rep right handed

Then,

5/8× x

= 5x/8

Since 4/5 are boys

1 - 4/5

1/4

Then,

5x/8 = 1/4

20x = 8

x = 8/20

x = 2/5

Therefore, the fraction of the girls in the school that are left handed is 2/5
