The figure, not drawn to scale, consists of 1 Rectangle X and 1 Square Y whose areas are in the ratio of 4 : 1. Given that
29 of Rectangle X is shaded, what fraction of Square Y is shaded?
Area of Rectangle X |
Area of Square Y |
4x9 = 36 u |
1x9 = 9 u |

Area of Rectangle X is the repeated identity.
Shaded area of Rectangle X is the same as the shaded area of Square Y.
LCM of 4 and 9 = 36
Fraction of Square Y that is shaded
=
