Answer 2

Answer:

The number of girls represents 8 parts of the ratio.

Let's find 1st   part first.

8 part is 1000

1st part is 1000 /8 =125

125 × 7 = 875

the percentage of boys in school = 875 ×100/1000

=> 87.5%

This question can also be considered as increasing in the ratio 8 :7

1000 ×7/8 = 875

the percentage of boys in school = 875 ×100/1000

=> 87.5%

You can also use direct proportion:

8/7 =1000/x

8x = 7×1000

x= 7×1000/8

x=875

the percentage of boys in school = 875 ×100/1000

=> 87.5%
