Captain America is packing equal numbers of apple slices and grapes for snacks. Captain America bags the apples slices in groups of 18 and the grapes in groups of 9. What is the smallest number of grapes he can pack?

18 grapes or two groups of grapes

Step-by-step explanation:

since the minimum number of apple slices he will pack is 18, the minimum number of grapes (that will allow him to have an equal amount of both fruits) is 18 grapes, or 2 groups of grapes.
