Question

an 8 in. by 10 in. photo is reduced so that the width (the shorter dimension) is 3 in. what is the length of the reduced photo

Answer 1

The length = 3.75 inches

Explanation:

Answer 2

Explanation:

The length can be found by setting up a proportion. If the width is reduced by some ratio, then the length will share the same ratio.

3 / 8 = x / 10 Multiply both sides by 10.

3 * 10 / 8 = x Multiply first

30/8 = x Divide next. You don't need to do it in this order.

3 6/8 Simplify

3 3/4 Give another choice

3.75

The length = 3.75 inches

If none of these are correct, please leave a note with your choices.
