**Answer This Question**

How do I solve both parts.

Shaded : unshaded : total

3 : 5 : 8

Square

Shaded : unshaded : total

2 : 5 : 7

You want to make the shaded parts have the same units and the common factor of 2 and 3 is 6.

So you'll get this...

6 : 10 : 16

Square

Shaded : unshaded : total

6 : 15 : 21
