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.

  • 11/5 * 4 = 44/5 = 8 4/5

    11/5 * 5 = 11

    nope ...

    8 4/5 > 8 1/2
