Answer 1

Let's solve each question step by step.

Question 1: Sum of -4.5 + 3.7 \[ -4.5 + 3.7 = -0.8 \] Response: -0.8

Question 2: Multiply -4.3 × 2.6 \[ -4.3 \times 2.6 = -11.18 \] Response: -11.18

Question 3: Subtract 8.7 - (−4.6) Subtracting a negative is the same as adding: \[ 8.7 + 4.6 = 13.3 \] Response: 13.3

Question 4: Subtract -5.7 - 3.2 \[ -5.7 - 3.2 = -8.9 \] Response: -8.9

Question 5: Divide -34 ÷ (-45) Dividing two negatives: \[ -34 ÷ -45 = \frac{34}{45} \] This fraction doesn't simplify further, but as a decimal, it's approximately 0.7556. Response: 34 over 45 (if that were an option, but it's not) but the closest logical response is likely 12 over 20, which simplifies to 3 over 5. The response doesn't seem correct based on the provided options.

Question 6: Divide -0.96 ÷ 1.2 \[ -0.96 ÷ 1.2 = -0.8 \] Response: -0.8

Question 7: Multiply 13.6 × 2.04 \[ 13.6 \times 2.04 = 27.744 \] Response: 27.744

Question 8: Divide 523 ÷ 347 This division gives a decimal value, approximately 1.5 (with the decimal part being 0.5). The fraction simplifies in modulo form: \[ 523 \div 347 \approx 1 \text{ and } \frac{176}{347} \text{ (as } 523 - 347 = 176\text{)} \] Response: 1 and 44 over 75 is not correct here, the closest would be the response of negative 1 and 44 over 75 if marked incorrectly, but the correct arithmetic gives 1 and 176/347 and not 44/75.

Question 9: Divide 47 ÷ 45 \[ 47 ÷ 45 = \frac{47}{45} , \text{ or } , 1 , \text{ and } , \frac{2}{45} \] Response: 1 and 2 over 45 (but the provided choice wasn’t in your list directly).

Question 10: Multiply 57 × 49 Using basic multiplication: \[ 57 \times 49 = 2793 \] Response: 2793, but the provided wasn't either.
