The square is divided into 4 parts, F, G, H and J. F and G form
12 of the square. The area of J is double of the area of H, while the ratio of the area of G to the area of F is 1 : 3. What fraction of the square is the sum of the area of G and H? Leave your answer in the simplest form.

H |
G |
F |
H + J |

Since F and G form
12 of the square, the sum of the areas of F and G is the same as the sum of the areas of H and J.
Sum of G and H
= 9 u + 4 u
= 13 u
Area of the square
= 8 u + 4 u + 9 u + 3 u
= 24 u
Fraction of the sum of the areas of G and H to the whole square =
