Question

I REALLY NEED HELP: Greg uses an overhead projector to enlarge a rectangular drawing to a width of 300mm. The original drawing is 60 mm wide by 80mm high. What is the height of the projected image?

Answer 1

height = 400mm high

Explanation:

if 300/60=5

so 80x5=400.

Answer 2

The height is 400 mm high.

60 reaches 300 by a factor of 5
so if you do 80 x 5 you get 400.
