# Can you help me with my math homework on similar polygons?

The original chart is 4 inches by 5 inches.If she uses a scale factor of 5:11, will the chart fit on a sheet of paper 8 1/2 inches by 11 inches?

You can find the size of the enlarged chart like so:

11 / 5 = Some decimal

Some decimal X 4 = answer height

Some decimal X 5 = answer width

The first step is the only tricky one:

when scaling up, always put the big number first: 11 / 5

when scaling down, put the little one first: 5 / 11

Glad to help.
