Michael and Rael had some money at first. Michael received 2 times as much money as Rael every fortnight. At the end of 4 fortnights, both of them had the same amount of money. If Rael had $1210 at first and Michael had $1870 at the end of those 4 fortnights, what is the ratio of Michael's money to the total amount of money at first?

$1870 |
Amount that Rael received every fortnight
= 1870 - 1210
= $660
1 u = 660
Amount that Michael received every fortnight
= 2 u
= 2 x 660
= $1320
Amount that Michael had at first
= 1870 - 1320
= $550
Total amount that Michael and Rael had at first
= 1210 + 550
= $1760
Michael's amount : Total amount
550 : 1760
5 : 16
Answer(s): 5 : 16
