Answer

$\frac{16}{15}$

Steps

Step 1 ：First, we need to simplify the expression by evaluating the exponents: $3^{- 1} = \frac{1}{3}$ , $5^{- 1} = \frac{1}{5}$ , and $2^{- 1} = \frac{1}{2}$

Step 2 ：Next, we perform the addition operation in the numerator: $\frac{1}{3} + \frac{1}{5} = \frac{5 + 3}{15} = \frac{8}{15}$

Step 3 ：Finally, we perform the division operation: $\frac{\frac{8}{15}}{\frac{1}{2}} = \frac{8}{15} \times \frac{2}{1} = \frac{16}{15}$

Step 4 ： $\frac{16}{15}$
