Clara multiplies (negative 6) (negative 7) (negative 1) and gets 42.

Question

Is her answer reasonable?
No, because the solution should have a negative answer.
No, because the solution should have a positive answer.
Yes, because the solution should have a negative answer.
Yes, because the solution should have a positive answer.

Answer 1

To determine the correctness of Clara's answer, we need to analyze the multiplication of the three negative numbers: (-6), (-7), and (-1).

1. The product of two negative numbers is positive. So, first we multiply -6 and -7: \[ (-6) \times (-7) = 42 \]

2. Next, we multiply this positive result by the third negative number (-1): \[ 42 \times (-1) = -42 \]

Thus, the final answer is -42, not 42.

Now we can analyze the answer choices:

• Clara got 42, but the correct answer should be -42.
• Therefore, her answer is not reasonable.

The correct choice is: No, because the solution should have a negative answer.
