The square is divided into 4 parts, K, L, M and N. K and L form
12 of the square. The area of N is double of the area of M, while the ratio of the area of L to the area of K is 1 : 5. What fraction of the square is the sum of the area of L and M? Leave your answer in the simplest form.

Since K and L form
12 of the square, the sum of the areas of K and L is the same as the sum of the areas of M and N.
Sum of L and M
= 5 u + 6 u
= 11 u
Area of the square
= 12 u + 6 u + 5 u + 1 u
= 24 u
Fraction of the sum of the areas of L and M to the whole square =
