You're Right!


There are 64 triangles in the design, each just the same size.

40 of the triangles are shaded purple. We can make the fraction 40/64 to show what part of the triangles are shaded purple.


40/64 can be put into lowest terms.

The G.C.F. of 40 and 64 is 8.

40 divided by 8 = 5
64 divided by 8 = 8

So, 40/64 = 5/8.
