Question

If the ratio of soccer balls to footballs is 7:6 and the ratio of footballs to basketballs is 2:1, what is the ratio of soccer balls to basketballs?

Answer 1

let soccer balls be s, football be f and basketball be b.

s:f is 7:6
f:b is 2:1
f:b can also then be written as 6:3 (multiply by 3)
therefore s:f:b is 7:6:3

therefore ratio of s:b is 7:3
