Nora and Abi went shopping with a total of $744. After Nora spent
56 of her money and Abi spent $60, the ratio of Abi's money became 3 times as much as Nora's money. Find the ratio of Nora's money to Abi's money at first.

- 5 u |
- 60 |
| After |

| Comparing between Nora and Abi in the end |
1 u |
3 u |
Total amount that Nora and Abi had at first
= 6 u + 3 u + 60
= 9 u + 60
9 u + 60 = 744
6 u + 5 u = 744 - 60
9 u = 684
1 u = 684 ÷ 9 = 76
Amount that Nora had at first
= 6 u
= 6 x 76
= $456
Amount that Abi had at first
= 744 - 456
= $288
At first
Nora : Abi
456 : 288
19 : 12
Answer(s): 19 : 12
