The figure, not drawn to scale, is made up of Square M and Rectangles N and P. The area of Square M is
23 of the total area of Rectangles N and P.
13 of Square M is shaded.
14 of Rectangle N is shaded.
15 of Rectangle P is shaded. What fraction of the figure is unshaded?

Comparing M and the
total of N and P |
2x3 =
6 u |
3x3 =
9 u |
| Total |
3x2 =
6 u |
4x1 =
4 u |
5x1 =
5 u |
| Shaded |
1x2 =
2 u |
1x1 =
1 u |
1x1 =
1 u |
| Unshaded |
2x2 =
4 u |
3x1 =
3 u |
4x1 =
4 u |
The area of M is repeated. Make the area of M the same. LCM of 2 and 3 is 6.
When M is 6 u, the total areas of N and P is 9 u.
Then adjust the values of N and P so that the total areas of N and P is equal to 9 u.
Unshaded areasTotal area =
4 + 3 + 4 6 + 3 + 4 =
