Given the ratios A to B is 2 to 3, B to C is 3 to 4, and A to D is 4 to 5, what is the ratio of C to D?

Explanation

First, find A to C by multiplying A:B and B:C ratios: (2/3) × (3/4) = 1/2. Then, calculate C to D by taking the reciprocal of A:C and multiplying by A:D: (2) × (4/5) = 8/5, which corresponds to 8:5. Therefore, the ratio C:D is 8:5.
