The least number of boxes Sharon should buy is 5 boxes.

Explanation:

Given,

Number of cards in box = 12

Number of stamps in packages = 20

We will find least common multiple of 12 and 20.

12 = 12,24,36,48,60,.....

20 = 20,40,60,80,....

The LCM of 12 and 20 is 60.

Now,

12 cards = 1 box

60 cards =
$(60)/(12)\ boxes$

60 cards = 5 boxes

The least number of boxes Sharon should buy is 5 boxes.
