Answer:
<h2>17/35</h2>
Step-by-step explanation:
We need to get all the fractions with a common denominator before we can solve the problem.
The only fractions that have a common multiple are 1/7 and 3/21, so we'll add these first and then add 1/5.
1/7 = 3/21
Add

6/21 = 30/105
1/5 = 21/105

Simplify
