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.

math 
Damon,
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 :) 
math 
mykala,
damon, how did you come up with the number 5 as least common multiple 1/6,1/3,2/5

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