The figure, not drawn to scale, consists of 1 Rectangle J and 1 Square K whose areas are in the ratio of 3 : 1. Given that
111 of Rectangle J is shaded, what fraction of Square K is shaded?
Area of Rectangle J |
Area of Square K |
3x11 = 33 u |
1x11 = 11 u |

Area of Rectangle J is the repeated identity.
Shaded area of Rectangle J is the same as the shaded area of Square K.
LCM of 3 and 11 = 33
Fraction of Square K that is shaded
=
