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

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