The figure, not drawn to scale, consists of 1 Square Y and 1 Circle Z whose areas are in the ratio of 3 : 1. Given that
18 of Square Y is shaded, what fraction of Circle Z is shaded?
Area of Square Y |
Area of Circle Z |
3x8 = 24 u |
1x8 = 8 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 3 and 8 = 24
