Answer 2

To solve the given expression:

8/5 × 3/4 + 11/8 + 18/7 × 4/9 + 15/14 34/74 × 48/55 - 34/74 × 48/55 45/46 × 3/51 - 45/46 × 3/51

Let's calculate it step by step:

Step 1: Multiply the fractions within each multiplication operation:

8/5 × 3/4 = (8 × 3) / (5 × 4) = 24/20 = 6/5

18/7 × 4/9 = (18 × 4) / (7 × 9) = 72/63 = 8/7

34/74 × 48/55 = (34 × 48) / (74 × 55) = 1632/4070

45/46 × 3/51 = (45 × 3) / (46 × 51) = 135/2346 = 5/78

Step 2: Perform addition and subtraction operations from left to right:

6/5 + 11/8 + 8/7 + 15/14 = [(6 × 8) + (11 × 5) + (8 × 5) + (15 × 2)] / (5 × 8) = (48 + 55 + 40 + 30) / 40 = 173/40

1632/4070 - 34/74 × 48/55 = 1632/4070 - 1632/4070 = 0

5/78 - 45/46 × 3/51 = 5/78 - 5/78 = 0

So, the simplified expression is:

173/40 + 0 + 0 = 173/40
