$1840 |
Amount that Ken received every week
= 1840 - 1360
= $480
1 u = 480
Amount that Michael received every week
= 3 u
= 3 x 480
= $1440
Amount that Michael had at first
= 1840 - 1440
= $400
Total amount that Michael and Ken had at first
= 1360 + 400
= $1760
Michael's amount : Total amount
400 : 1760
5 : 22
Answer(s): 5 : 22
