Pete, Chris, and Dina realized that the number of A’s they each received on their report cards were in a ratio of 4:2:5. If Pete got 14 more A’s than Chris, how many A’s did Dina get?

Step-by-step explanation:

Given

Peter = 14 more A's than Chris

Required

How many A’s did Dina get?

The order of the ratio is Peter: Chris: Dina

This implies that

Considering Peter and Chris

Let the number of Chris' A's be represented by A

This implies that:

Peter's = 14 + A

And as such;

Convert ratio to division

Multiply both sides by A

Subtract A from both sides

This means that;

Chris answered 14 while Pete answered 28 (14 + 14)

Considering Chris and Dana

Replace Chris with 14

Convert ratio to division

Cross Multiplication

Divide both sides by 2

Hence, Dina had 35 A's
