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

1 u |
Area of Rectangle M is the repeated identity.
Shaded area of Rectangle M is the same as the shaded area of Square N.
LCM of 3 and 9 = 9
