The figure, not drawn to scale, consists of 1 Square Q and 1 Circle R whose areas are in the ratio of 2 : 1. Given that
415 of Square Q is shaded, what fraction of Circle R is shaded?

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