The figure, not drawn to scale, consists of 1 Rectangle Y and 1 Square Z whose areas are in the ratio of 2 : 1. Given that
25 of Rectangle Y is shaded, what fraction of Square Z is shaded?
| Area of Rectangle Y |
Area of Square Z |
| 2x5 = 10 u |
1x5 = 5 u |
| Unshaded area |
Shaded area |

4 u |
Area of Rectangle Y is the repeated identity.
Shaded area of Rectangle Y is the same as the shaded area of Square Z.
LCM of 2 and 5 = 10
Fraction of Square Z that is shaded
=
