Answer:

The answer is 2/21

Explanation:

Step 1: simplify 2/7

Step 2: simplify 3/7

Step 3: Adding fractions which have a common denominator

So it would be - 3+2/7 = 5/7

So the new equation would be 17/21 - 5/7

Step 4: simplify 17/21

Step 5: Calculating the LCM (Least Common Multiple)

The LCM is 21

17-(5 × 3)/21 = 2/21
