Abi and Min went shopping with a total of $260. After Abi spent
45 of her money and Min spent $60, the ratio of Min's money became 5 times as much as Abi's money. Find the ratio of Abi's money to Min's money at first.

| After |

| Comparing between Abi and Min in the end |
1 u |
5 u |
Total amount that Abi and Min had at first
= 5 u + 5 u + 60
= 10 u + 60
10 u + 60 = 260
5 u + 4 u = 260 - 60
10 u = 200
1 u = 200 ÷ 10 = 20
Amount that Abi had at first
= 5 u
= 5 x 20
= $100
Amount that Min had at first
= 260 - 100
= $160
At first
Abi : Min
100 : 160
5 : 8
Answer(s): 5 : 8
