Ken mixes 3 5/8 pounds of raisins with 4 1/2 pounds of almonds. then, he separates the mixture into bags with 5/8 pounds of the mixture in each bag.

how many bags of the mixture does ken make

First, we need to find the total weight of the mixture of raisins and almonds. We can add the two weights together:

3 5/8 + 4 1/2 = 29/8 + 9/2 = 29/8 + 36/8 = 65/8 pounds

Next, we divide the total weight of the mixture by the weight of each bag:
(65/8) / (5/8) = 65/8 * 8/5 = 65/5 = 13 bags

Therefore, Ken makes 13 bags of the mixture.
