The figure, not drawn to scale, consists of 1 Rectangle Y and 1 Square Z whose areas are in the ratio of 4 : 1. Given that
215 of Rectangle Y is shaded, what fraction of Square Z is shaded?
Area of Rectangle Y |
Area of Square Z |
4x15 = 60 u |
1x15 = 15 u |

Area of Rectangle Y is the repeated identity.
Shaded area of Rectangle Y is the same as the shaded area of Square Z.
LCM of 4 and 15 = 60
Fraction of Square Z that is shaded
=
