The figure, not drawn to scale, consists of 1 Square Y and 1 Circle Z whose areas are in the ratio of 4 : 1. Given that
16 of Square Y is shaded, what fraction of Circle Z is shaded?
Area of Square Y |
Area of Circle Z |
4x3 = 12 u |
1x3 = 3 u |

Area of Square Y is the repeated identity.
Shaded area of Square Y is the same as the shaded area of Circle Z.
LCM of 4 and 6 = 12
