Please determine if it is a problem, either a "How many groups" or "How many units in 1 group" and provide an explaination and solution. 

13. For each of the following problems, determine if it
is a problem for 3 ÷ or for ÷ 3. If so, say what
type of division applies (how-many-groups or
how-many-units-in-1-group) and explain how you
can tell. Otherwise, say how the problem could be
solved (if it can be solved).
