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 : 6. What fraction of the square is the sum of the area of J and F? Leave your answer in the simplest form.
| J |
H |
G |
F |
H + J |
G + F |
| 2x7 |
1x7 |

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 J and F
= 14 u + 3 u
= 17 u
Area of the square
= 14 u + 7 u + 18 u + 3 u
= 42 u
Fraction of the sum of the areas of J and F to the whole square =
