The square is divided into 4 parts, P, Q, R and S. P and Q form
12 of the square. The area of S is double of the area of R, while the ratio of the area of Q to the area of P is 1 : 6. What fraction of the square is the sum of the area of Q and R? Leave your answer in the simplest form.

Since P and Q form
12 of the square, the sum of the areas of P and Q is the same as the sum of the areas of R and S.
Sum of Q and R
= 18 u + 7 u
= 25 u
Area of the square
= 14 u + 7 u + 18 u + 3 u
= 42 u
Fraction of the sum of the areas of Q and R to the whole square =
