Question

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

Answer 1

this is a ration problem height/width= new ht /new wdth
height=32.5
width=42.9
new ht =x
new wdth=3.3

i use height instead of tall and watch your units in these kind of problems

so plug in your values

32.5/42.9=x/3.3 cross multiply
3.3(32.5)=42.9x divide both sides by 42.9 isolating x
3.3(32.5)/42.9 =x
x=???
