$1680 |
Amount that Jeremy received every month
= 1680 - 1400
= $280
1 u = 280
Amount that Liam received every month
= 3 u
= 3 x 280
= $840
Amount that Liam had at first
= 1680 - 840
= $840
Total amount that Liam and Jeremy had at first
= 1400 + 840
= $2240
Liam's amount : Total amount
840 : 2240
3 : 8
Answer(s): 3 : 8
