Sharon can buy cards in boxes of 12 and stamps in packages of 20 what is the least number of boxes of cards she should buy?
-Dominant- [34]

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

Step-by-step 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 = \frac{60}{12}\ boxes

60 cards = 5 boxes

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

Why would negative numbers not make sense for the values of the variables
Naily [24]
One reason that negative numbers would not make sense for values of the variables is that the solution having a negative value is not valid. It might be that the expression represents a real word problem and a negative value will not make any sense. Hope this helps.
