What would make finding the answer a bit easier, is converting them into improper fractions. You would turn that first fraction to

and the second fraction to

. (You are dividing a negative by a negative, therefore, your answer would be a positive.
Let's follow the procedure of keeping, switching, and flipping. You keep the first improper fraction, switch the division sign to a multiplication sign, and flip the second fraction. That would make it :

×

.
You multiply the 9 and the 2, you get 18. You multiply the 3 and the 4, you get 12. That makes it

. This, converted to a mixed fraction, makes 1

., which is the same as 1

. Your answer is the
SECOND CHOICE.
