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.

30 is a common multiple of all the denominators
12/30
5/30
10/30
now order them 
how did you get the denominators to be the same?

5/30,10/30,12/30
