Gerald is putting mints into a bag for party favors. He has 36 blue mints and 42 red mints. Each bag will have either red mintsor blue mints. All the bags have the same number of mints? What is the greatest numbers of mints Gerald can put in each bag?

Gerald can put 6 blue mints and 7 red mints in each bag. The greatest number of mints IN ALL he can put in his bag is 13 to have no more left remaining. (6+7=13)

If you find the greatest common factor for both 36 and 42, it would be 6. You’d divide 36 by 6 to get 6. While 42 divided by 6 is 7.
