What is the greatest number of boxes she can make?

Question

Megan has 20 brownies and 40 cupcakes. She wants to put equal number or brownies and cupcakes in each box.

Answer 1

Did you mean She wants to put equal number OF brownies and cupcakes in each box?

 

Does this mean, for example, that she could put 1 brownie and 2 cupcakes in each box?  Then 20 boxes could be made up.

 

But if the same number of brownies and cupcakes were required, then 20 boxes (containing just one of each), and 20 cupcakes would be left over--unless it would be acceptable to put two cupcakes in each of ten other boxes, 

 

Do you see that the wording is imprecise?

Answer 2

20.... if that's too much  then

 

10.....  if that's too much then

 

5

 

but the GCF of 20 and 40 is 20
