Question

When their reports cards came back, Pete, Chris, and Dina realized that they shared an amount of A’s in the ratio 4:2:5. If Pete got 14 more A’s than Chris, how many A’s did Dina get?

Answer 1

35

Explanation:

Answer 2

35

Explanation:

The difference between Pete's number of "ratio units" (4) and Chris's (2) is ...

... 4 - 2 = 2

This difference represents 14 As, so each "ratio unit" stands for ...

... 14/2 = 7

As. Then Dina's 5 "ratio units" correspond to 5*7 = 35 As.
