Answer

Final Answer: $\boxed{\frac{8}{15}}$

Steps

Step 1 ：Convert the fractions to have a common denominator: $\frac{1}{5} = \frac{3}{15}$ and $\frac{1}{3} = \frac{5}{15}$

Step 2 ：Add the two fractions together: $\frac{3}{15} + \frac{5}{15} = \frac{8}{15}$

Step 3 ：So, Ali has cut off $\frac{8}{15}$ of the pipe in total.

Step 4 ：Final Answer: $\boxed{\frac{8}{15}}$
