The figure, not drawn to scale, consists of 1 Square X and 1 Circle Y whose areas are in the ratio of 2 : 1. Given that
115 of Square X is shaded, what fraction of Circle Y is shaded?
Area of Square X |
Area of Circle Y |
2x15 = 30 u |
1x15 = 15 u |

Area of Square X is the repeated identity.
Shaded area of Square X is the same as the shaded area of Circle Y.
LCM of 2 and 15 = 30
Fraction of Circle Y that is shaded
