Question

The ratio of the number of boy campers to the number of girl campers was 8:7. If there were a total of 195 campers, how many boy campers were there and how many girl campers

Answer 1

8x - amount of boys
7x- amount of girls 

8x + 7x = 195
 
15x= 195  ( divide by 15)

x= 13

8x = 8 x 13 = 104

7x = 7 x 13= 91 

there are 104 boys, and 91 girls.
