Answer:
There are 9 distinct possible values for q.
Step-by-step explanation:
Let ab be a positive two-digit integer.
- a×b=q=7k from some positive integer k.
- either a or b is 7, since 7 is a prime number and k can be maximum 9.
- assume a=7, then b can be 1,2,3,4,5,6,7,8,9
- b cannot be 0 because a×b=q has to be positive
- if b=7, then a can be 1,2,3,4,5,6,7,8,9
- in both cases there are 9 distinct values for q, which are 7,14,21,28,35,42,49,56,63
