Answer

$10 \frac{23}{48}$ is the final answer

Steps

Step 1 ：Convert mixed numbers to improper fractions: $5 \frac{15}{16} = \frac{95}{16}$ , $2 \frac{7}{8} = \frac{23}{8}$ , and $1 \frac{1}{3} = \frac{4}{3}$

Step 2 ：Find a common denominator for the fractions: $lcm (16, 8, 3) = 48$

Step 3 ：Convert the fractions to have the common denominator: $\frac{95}{16} = \frac{285}{48}$ , $\frac{23}{8} = \frac{138}{48}$ , and $\frac{4}{3} = \frac{64}{48}$

Step 4 ：Add the fractions: $\frac{285}{48} + \frac{138}{48} + \frac{64}{48} = \frac{487}{48}$

Step 5 ：Convert the improper fraction back to a mixed number: $\frac{487}{48} = 10 \frac{23}{48}$

Step 6 ： $10 \frac{23}{48}$ is the final answer
