First, find common denominators. The smallest common denominator is 12. Multiply 4 to numerator and denominator for -9/3 to get it over 12
(-9/3)(4/4) = -36/12
- 5/12 - (-36/12)
Simplify. Note that when there are two negatives, it becomes a positive
- (-36/12) = + 36/12
-5/12 + 36/12 = 31/12
31/12 is your improper fraction answer.
Simplify. Change it into mixed fraction.
31/12 = 2 7/12
2 7/12 is your mixed fraction answer.
hope this helps
