57 pens per bag

21 pencils per bag

9 erasers per bag

Step-by-step explanation:

Here, we are to distribute a specific portion of each of the items in each of the gift bags.

Thus, what we do is to divide the total number of each item by 3 to get exactly the number of each items that would be in each of the gift bags

For the pens, we have 171/3 = 57 pens per bag

For the pencils, we have 63/3 = 21 pencils per bag

For the erasers, we have 27/3 = 9 erasers per bag
