$1920 |
Amount that Oscar received every week
= 1920 - 1320
= $600
1 u = 600
Amount that Michael received every week
= 2 u
= 2 x 600
= $1200
Amount that Michael had at first
= 1920 - 1200
= $720
Total amount that Michael and Oscar had at first
= 1320 + 720
= $2040
Michael's amount : Total amount
720 : 2040
6 : 17
Answer(s): 6 : 17
