Answer 1

Answer:

66 girls

Step-by-step explanation:

3 : 5 : : 40 : x

x = (5 x 40)/3

x = 66

Answer 2

Answer:

girls = 25

boys = 15

Step-by-step explanation:

Ratio of boys = 3

Ratio of girls = 5

First, add 3 and 5

i.e. 3+5 = 8

then, divide 40 by 8 that will let you find out how many students is represented by each number in the ratio.

40/8 = 5

then multiply 5 to both, 3 and 5 , to find out the number of boys and girls.

5×3 = 15 ( boys)

5×5= 25 ( girls)
