Multiply −1 1/6

by 7. Write the answer as a mixed number.

1 answer

To multiply \(-1 \frac{1}{6}\) by \(7\), first, we convert the mixed number to an improper fraction.

  1. Convert \(-1 \frac{1}{6}\) to an improper fraction: \[ -1 \frac{1}{6} = -\left(1 \times 6 + 1\right)/6 = -\frac{7}{6} \]

  2. Now multiply \(-\frac{7}{6}\) by \(7\): \[ -\frac{7}{6} \times 7 = -\frac{7 \times 7}{6} = -\frac{49}{6} \]

  3. Convert \(-\frac{49}{6}\) back to a mixed number:

    • Divide \(49\) by \(6\): \[ 49 \div 6 = 8 \quad \text{(remainder: 1)} \]
    • So, \(-\frac{49}{6}\) can be expressed as: \[ -8 \frac{1}{6} \]

Thus, the answer is: \[ \boxed{-8 \frac{1}{6}} \]
