Answer:
12 bouquets
Step-by-step explanation:
Determine what the greatest common factor is in this case...
72/12 = 6 red roses
60/12 = 5 pink roses
48/12 = 4 yellow roses
As you can see the greatest common factor is 12. Therefore the greatest number of bouquets that the florist can make if no roses are left over should be 12 bouquets.
