Ali has a $10 \mathrm{ft}$ piece of pipe that she needs to cut down. She cuts off $\frac{1}{5}$ and she cuts off $\frac{1}{3}$. Evaluate the following expression to determine how much pipe she has cut off in total: \[ \frac{1}{5}+\frac{1}{3} \]

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: \(\boxed{\frac{8}{15}}\)
