Final answer:
Each friend will get 3/5 of a pack of football cards when 3 packs are equally shared among 5 friends. This is found by dividing the total packs by the number of friends.
Step-by-step explanation:
To determine how much of a pack of football cards each friend will get, we need to divide the total packs of cards by the number of friends. In this case, there are 3 packs of football cards and 5 friends. If we divide 3 packs among 5 friends, each friend would get 3/5 of a pack.
To find this fraction, you could imagine splitting each pack into 5 equal parts, so you would have a total of 15 parts (because 3 packs × 5 parts per pack = 15 parts). Then, these 15 parts would be shared equally among the 5 friends, so each friend would get 3 parts. Since each part represents 1/5 of a pack, 3 parts would be 3 times 1/5, which is 3/5.
