The figure, not drawn to scale, consists of 2 squares Q and R whose areas are in the ratio of 2 : 1. Given that
49 of Square Q is shaded, what fraction of Square R is shaded?
Area of Square Q |
Area of Square R |
2x9 = 18 u |
1x9 = 9 u |

Area of Square Q is the repeated identity.
Shaded area of Square Q is the same as the shaded area of Square R.
LCM of 2 and 9 = 18
Fraction of Square R that is shaded
