What is the number of boys and girls campers if there's 195 campers and the ratio is 8 : 7

Boys : girls

8 : 7

Total = 15

Boys = 8/15 * 195

= 8 * 13

=104 boys

Girls could be found in two ways

WAY 1

195 - 104 = 91 girls

OR

WAY 2

Girls = 7/15 * 195

= 7 * 13

= 91

First of all, 8 + 7 = 15, so we divide 195 by 15, and get 13. Each unit has 13 children.

The ratio is: Boys Girls

8 : 7

Now all we have to do is multiply. 8 x 13 = 104. 7 x 13 = 91.

Therefore, there are 104 boys and 91 girls.
