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

Since N and P form
12 of the square, the sum of the areas of N and P is the same as the sum of the areas of Q and R.
Sum of R and N
= 12 u + 1 u
= 13 u
Area of the square
= 12 u + 6 u + 5 u + 1 u
= 24 u
Fraction of the sum of the areas of R and N to the whole square =
