Fred and Ian had some money at first. Fred received 2 times as much money as Ian every day. At the end of 4 days, both of them had the same amount of money. If Ian had $1080 at first and Fred had $1860 at the end of those 4 days, what is the ratio of Fred's money to the total amount of money at first?

$1860 |
Amount that Ian received every day
= 1860 - 1080
= $780
1 u = 780
Amount that Fred received every day
= 2 u
= 2 x 780
= $1560
Amount that Fred had at first
= 1860 - 1560
= $300
Total amount that Fred and Ian had at first
= 1080 + 300
= $1380
Fred's amount : Total amount
300 : 1380
5 : 23
Answer(s): 5 : 23
