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
