We are given the following information:
each person uses 3/8 a box
there are 6 boxes
Because each box is [tex]\frac{8}{8}[/tex], and there are 6 boxes, we know that 1 person is [tex]\frac{3}{8*6}[/tex], or [tex]\frac{3}{48}[/tex].
In order to find how many people can use the 6 boxes, we can divide it by 3 (for each use):
48 / 3 = 16
Therefore, 16 people can share the worms.
Hope this helps! :)
