Alright so:
?p/?q ---> positive quotient
Let's try with a bunch of numbers.
______
a.) positive p and negative q
If we divide +6 by -3, we would get -2, which is negative. So this is the wrong answer.
b.) positive p and positive q
If we divide +6 by +3, we would get +2, which is positive. This is a correct answer.
c.). negative p and negative q
If we divide -6 by -3, we would get +2, which is positive. This is also a correct answer.
d.) negative p and positive q
If we divide -6 by +3, we would get -2, which is negative. This is a wrong answer.
________
The positive answers are b & c, and so the correct answer is f, which states that b & c are the ones that give a positive quotient.
Hope this clears it.
