Cody and Rael had some money at first. Cody received 2 times as much money as Rael every month. At the end of 2 months, both of them had the same amount of money. If Rael had $1200 at first and Cody had $2340 at the end of those 2 months, what is the ratio of Cody's money to the total amount of money at first?

$2340 |
Amount that Rael received every month
= 2340 - 1200
= $1140
1 u = 1140
Amount that Cody received every month
= 2 u
= 2 x 1140
= $2280
Amount that Cody had at first
= 2340 - 2280
= $60
Total amount that Cody and Rael had at first
= 1200 + 60
= $1260
Cody's amount : Total amount
60 : 1260
1 : 21
Answer(s): 1 : 21
