To find out how many pears each friend will get, we need to first determine the total number of pears Jen has.
Jen has 3 bags of pears, with each bag containing 5 pears. So, the total number of pears is:
\[ 3 \text{ bags} \times 5 \text{ pears/bag} = 15 \text{ pears} \]
Now, if Jen gives the same number of pears to 4 friends, we need to divide the total number of pears by 4:
\[ 15 \text{ pears} \div 4 \text{ friends} = 3.75 \text{ pears/friend} \]
Since we usually cannot divide pears into fractions when distributing them, we can conclude that each friend could reasonably receive 3 pears, and there would be 3 pears left over.
However, among the options provided (2, 3, 4, 5), the closest sensible quantity each friend would receive is 3 pears.
So, each friend would get 3 pears.
