The figure, not drawn to scale, consists of 1 Rectangle Q and 1 Square R whose areas are in the ratio of 3 : 1. Given that
19 of Rectangle Q is shaded, what fraction of Square R is shaded?
Area of Rectangle Q |
Area of Square R |
3x3 = 9 u |
1x3 = 3 u |
Unshaded area |
Shaded area |

1 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 3 and 9 = 9
