Problem Teachers' Notes Hint Solution

Route Product

1. 5 x 0.1 = 0.5
2. 5 x 2 x 0.5 = 5
3. 5 x 2 x 2 x 0.1 = 2
4. 5 x 2 x 0.5 x 1 x 0.1 = 0.5
5. 3 x 0.5 = 1.5
6. 3 x 2 x 0.1 = 0.6
7. 3 x 2 x 0.1 = 0.6
8. 3 x 0.5 x 1 x 0.1 = 0.15
9. 4 x 1 x 0.1 = 0.4
10. 4 x 1 x 2 x 0.5 = 4
11. 4 x 1 x 2 x 2 x 0.1 = 1.6
12. 4 x 0.5 x 0.5 = 1
13. 4 x 0.5 x 2 x 0.1 = 0.4
14. 4 x 0.5 x 2 x 0.1 = 0.4

Therefore largest is 5 (route 2) and smallest is 0.15 (route 8)
