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

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