Step-by-step explanation:

Givens

Initially, the ham weighed $15 \frac{1}{8}lb$ , which is equivalent to $\frac{121}{8}lb$ .After cooking and without bone, the ham weighed $1\frac{3}{5} lb$ less, which is equivalent to $\frac{8}{5} lb$ .

To know the total amount of ham we have to serve, we need to subtract

$\frac{121}{8}- \frac{8}{5}=\frac{605-64}{40}=\frac{541}{40}$

So, there is 541/40 pounds to serve.

If each serving has 5/16 pounds of the ham, then we need to divide this with the total pounds available, and that would give the total number of servings

$\frac{541}{40} \div \frac{5}{16}=\frac{541}{40} \times \frac{16}{5}= \frac{8656}{200} \approx 43.28$

So, there are 43.28 possible serving. However, we need to round this to the integer because we cannot serve a uncomplete plate.

Therefore, she can provide 43 complete servings with 5/16 pounds of ham.
