Jerome, Kevin, & Seth shared a submarine sandwich. Jerome ate 1/2 of the sandwich, Kevin ate 1/3 of the sandwich and Seth ate the rest. What is the ration of Jerome's share to Kevin's share to Seth's share?
1. 2:3:6
2. 2:6:3
3.3:1:2
4.3:2:1
5.6:3:2
please help!

The least common denominator of 1/2 and 1/3 is 6.
1/2 = 3/6
1/3 = 2/6
How much does that leave for Seth? 
Get a common denominator
If you have a/6 and b/6 and c/6, then a:b:c would be the ratio and a+b+c=6 
1/3 for Seth. The ratio is 3:2:1
