Answer: There are 13 packages that Tim can make.
Explanation:
Since we have given that
Number of pairs of headphones = 39
Number of music players = 13
We need to find the greatest number of packages.
For this we need to find the H.C.F. of 39 and 13.
and H.C.F of 39 and 13 = 13
So, there are 13 packages that Tim can make.
