Answer 1

$7 \frac{2}{15 } + 5 \frac{2}{3} + 9 \frac{3}{15}$

Convert mixed number to improper fraction.

$\frac{107}{15} + \frac{17}{3} + \frac{148}{15}$

Then change all the denominators into a same number

$\frac{107}{15} + \frac{85}{15} + \frac{148}{15}$

Add all the numerators but let all the denominators be same.

$\frac{107+85+148}{15} = \frac{340}{15}$

Change the improper fraction back into a mixed number..

$22 \frac{10}{15}$ I see that we can still simplify the fraction.. 

$22 \frac{10}{15} = 22 \frac{2}{3}$

Your final answer is C. $22 \frac{2}{3}$
