Question

How do I solve this problem?Mary reduced the size of a painting to a width of 3.3 inches. What is the new height of it was originally 32.5 inches tall and 42.9 inches wide? Round your answer to the nearest tenth.

Answer 1

Given the follow equivalence

`(Oldwidth)/(Oldheight)=(Newwidth)/(Newheight)`

where

old width=42.9

Old height= 32.5

New width=3.3

then

`(42.9)/(32.5)=(3.3)/(Newheight)`
`Newheight=3.3*(32.5)/(42.9)`
`Newheight=2.5`

New height is 2.5 inches
