Mary reduced the size of a painting to a width of 3.3 in what is the height if it was originally 32.5 in tall and 42.9 in wide?

2.5 in

Step-by-step explanation:

From the question, we are informed that Mary reduced the size of a painting to a width of 3.3 in even though the original width was 42.9 in wide. This shows that the size of the painting was 3.3/42.9 = 1/13

Therefore, the height of it was originally 32.5 in will be:

= 1/13 × 32.5

= 2.5 in

Therefore, the height is 2.5 in.
