Question

The table below shows the widths and lengths, in feet, for different playgrounds. Which playgrounds have equivalent ratios of width to length?

12 15 20 16.5 Width
20 22.5 25 27.5 Length

Answer 1

The playground that is 12 ft by 20 ft has equivalent ratio with the playground that is 16.50 ft by 27.50 ft.

Width 12 15 20 16.50
Length 20 22.50 25 27.50

We divide the width by its length.
12/20 = 0.60
15/22.50 = 0.67
20/25 = 0.80
16.50 / 27.50 = 0.60
