Question

There are 10 boys and 8 girls on the cross-country team. The ratio of boys to girls participating in track and field is proportional to the ratio of boys to girls on the cross-country team.

Which could be the number of boys and girls participating in track and field?

A.
12 boys and 10 girls

B.
14 boys and 12 girls

C.
15 boys and 12 girls

D.
16 boys and 14 girls

Answer 1

C is right because 10 is 5/5 and 8 would be 4/5 so  proportionally 15 is 5/5 and 12 is 4/5 cuz   2 can go in 10 five times and into 8 4 times. 3 can go into 15 five times and into 12 4 times.

Answer 2

c is the answer if you add 2 to both numbers it will give you 12 and 10
