Answer: C
Step-by-step explanation:

+

First, find the least common denominator (LCD) of the two fractions.
Multiples of 16: 16
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16
The LCD is 16.
Second, make the denominators the same as the LCD. / Your problem should look like:

+
Third, simplify. The denominators are now the same. / Your problem should look like:

+
Fourth, join the denominators. / Your problem should look like:
Fifth, simplify. / Your problem should look like:
Sixth, convert to mixed fraction. / Your problem should look like:
