Question

Tory has two similar picture frames in her bathroom. The ratio of the larger picture frame to the smaller picture frame is 5:2. If the perimeter of the smaller picture frame is 30 in, what is the perimeter of the bigger picture frame?

Answer 1

it's 75 in

Ratio of perimeter of larger square to perimeter of smaller square = 5:2

Let p = perimeter of larger frame
p:30 = 5:2
p/30 = 5/2
p = 30 * 5/2
p = 75
