Answer 2

To solve the given expressions, let's go through them one by one:

1. 610 × 700 / 3150 : 90 The division symbol is ambiguous in this case, so let's assume it means to divide the result of the multiplication by 90. Calculation: (610 × 700) / 3150 ÷ 90 = 427400 / 3150 ÷ 90 ≈ 136 ÷ 90 ≈ 1.511

2. 2600 × 40 / 67200 : 700 Again, the division symbol is ambiguous. Assuming it means to divide the result of the multiplication by 700. Calculation: (2600 × 40) / 67200 ÷ 700 = 104000 / 67200 ÷ 700 ≈ 1.547

3. 5050 × 50 / 348000 : 6005 Assuming the division symbol represents dividing the result of the multiplication by 6005. Calculation: (5050 × 50) / 348000 ÷ 6005 = 252500 / 348000 ÷ 6005 ≈ 0.364

4. 900 × 80 / 252000 : 9000 Assuming the division symbol represents dividing the result of the multiplication by 9000. Calculation: (900 × 80) / 252000 ÷ 9000 = 72000 / 252000 ÷ 9000 ≈ 0.08

Therefore, the results are approximately:

1. 1.511
2. 1.547
3. 0.364
4. 0.08
