Question

the ratio of girls to boys in a chess club was 6 : 2. there were 48 girls. how many total members were there in the club?

Answer 1

girls / boys : 6/2 = 48/b
cross multiply
(6)(b) = (2)(48)
6b = 96
b = 96/6
b = 16

so if there is 48 girls, then there is 16 boys for a total of 64 total members

Answer 2

Since the ratio is 6:2, girls:boys, we can do 48 girls divided by the ration so 48/6, which equals 8. Then, to get an equivalent ratio, we do 2 x 8 = 16. Finally, add 16 to 48 to get 64
