The figure, not drawn to scale, consists of 1 Rectangle L and 1 Square M whose areas are in the ratio of 3 : 1. Given that
415 of Rectangle L is shaded, what fraction of Square M is shaded?
Area of Rectangle L |
Area of Square M |
3x5 = 15 u |
1x5 = 5 u |
Unshaded area |

Area of Rectangle L is the repeated identity.
Shaded area of Rectangle L is the same as the shaded area of Square M.
LCM of 3 and 15 = 15
