The rhombus in each pair are similar. Find the scale factor of the smaller figure to the larger figure. Write scale factor like this: (ex. 1:7)

one rhombus' long sides are 42 and 42. the short side is 24.

the smaller rhombus' long sides are 35 and 35. the short side is 20.

What is the scale factor? Show all the work

First, let's find the ratio of the long sides of the two rhombuses:

42/35 = 6/5

Next, let's find the ratio of the short sides of the two rhombuses:
24/20 = 6/5

Since the ratios of the long sides and short sides are the same, the scale factor of the smaller figure to the larger figure is 6:5.
