hodyreva [135]

Answer:

3 1/3 gum balls per friend

Step-by-step explanation:

Packs of gum balls Pete has = 4

Each pack = 5 gum balls

Total gum balls Pete has = Number of packs of gum balls × Number of gum balls in each pack

= 4 × 5

= 20 gum balls

Pete gives the same number of gum balls to 6 friends.

Each friend gets = Total gum balls / number of friends

= 20 gum balls / 6 friends

= 3 2/6 gum balls per friend

= 3 1/3 gum balls per friend
