To convert the fraction \( -\frac{1}{7} \) into a decimal, you can divide -1 by 7.
When you perform the division:
\[
-1 \div 7 \approx -0.142857
\]
The decimal of \( -\frac{1}{7} \) is a repeating decimal:
\[
-0.142857142857\ldots
\]
Therefore, \( -\frac{1}{7} \) as a decimal number is \( -0.142857 \) (with the six digits "142857" repeating indefinitely). To represent it as a rounded decimal, you could write it as \( -0.143 \) if rounding to three decimal places.
