11/35 because u need to put common denominators for both fractions.
2/7 = 10/35 and 3/5 = 21/35
Then subtract
21/35 - 10/35 = 11/35

Answer:

11/35

Explanation:

First, you would have to make a common denominator. To do this, multiply these 2 denominator, 5 and 7. You should get 35. Then, you would have to make the numerator equal to the denominator. In this case, multiply 3 to 7 and 2 to 5. Now you have 21/35 and 10/35. Now subtract 21 from 10, and simplify if needed. I hope this helps!
