Answer:
9/35
Explanation:
To answer this question, you will need to find a common denominator.
The lowest common denominator between 7 and 5 is 35.
6/7 is equal to 30/35 and 3/5 is equal to 21/35
Use these numbers instead.
30/35 - 21/35 = 9/35
This number cannot be reduced any further, so it is the answer.
