Question

In a class of 40 student's,3/5 fraction of the total is girls how much is the boys

Answer 1

Explanation:

If 3/5 of the class is girls then 2/5 is boys.

Multiply 40 times 3/5 = 24

(40 times 3 divided by 5 = 24)

24 girls

Multiply 40 times 2/5 = 16

(40 times 2 divided by 5 = 16)

16 boys

Answer 2

16

Explanation:

Fraction of girls = 3/5 of 40 students

Fraction of boys = 1 - Fraction of girls

Fraction of girls = ( 3/5 ) × 40 = 24 girls

Fraction of boys = 1 - Fraction of girls = 1 - 3/5 = 2/5

Now, find the number of boys.

Number of boys = Fraction of boys × Total number of students

Number of boys = ( 2/5 ) × 40 = 16 boys
