This is simple division, but let's convert the mixed fractions into improper fractions. It will help later. Let's do it:



Let's divide them now:



Simplify as much as possible, before turning it into a mixed fraction again (they are both divisible by 4):


Now let's convert to an improper fraction. First, divide the numerator by the denominator, which has a reminder of 14. Then, get the quotient which is also 14, and put it all over 15 (denominator doesn't change). So, your final answer is:


Which is very very very close to 15, and so, I would go with C, 15.
