Mr. Gardner is making 6 treat bags. He has 185 chocolate-covered raisins to share evenly among the treat bags.
How many chocolate-covered raisins will be in each treat bag?
How many chocolate-covered raisins will be left over?

Answers

Answer:

30 chocolate covered rasins

5 left over

Step-by-step explanation:

Step 1: 185 Divided by 6 and that gets you 30, and some left over.

Step 2: Do 6 x 30 and that gets 180

Step 3: Do 185 subtract 180 and then you get 5

Step 4: So 30 chocolate coverd raisins will go in each bag, and 5 will be left over.
