The rules for adding or subtracting fractions is the same as adding or subtracting mixed numbers.
Rule for +/- Fractions/Mixed Numbers
1. Make them fractions - (turn all mixed numbers into impropers)
2. Find a common denominator.
3. Make equivalent fractions (if you are changing the denominators, you must change the numerators)
4. + or - numerators, keep the denominators the same
5. Simplify if needed.
