The figure, not drawn to scale, consists of 1 Rectangle Y and 1 Square Z whose areas are in the ratio of 3 : 1. Given that
112 of Rectangle Y is shaded, what fraction of Square Z is shaded?
Area of Rectangle Y |
Area of Square Z |
3x4 = 12 u |
1x4 = 4 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 3 and 12 = 12
