adam wants to compare the fractions 2/5, 1/6 and 1/3. he wants to order them from least to greatest and rewrite them so they all have the same denominator. explain how adam can rewrite the fractions.

least common multiple of
5
2*3
3
is
5*2*3 = 30
so use
2/5 = 12/30 (top and bottom by 6)
1/6 = 5/30 (top and bottom by 5)
1/3 = 10/30 (top and bottom by 10)
now put them in order :) 
damon, how did you come up with the number 5 as least common multiple 1/6,1/3,2/5

30, it says 30 is least common multiple of 5, 6 which is 2*3 and 3
