To determine which fraction has the lowest value among the given options, we can compare the fractions directly.
The fractions are:
- \(-\frac{1}{8}\)
- \(-\frac{5}{8}\)
- \(-\frac{7}{8}\)
- \(-\frac{3}{8}\)
Since all the fractions are negative, the one with the highest absolute value will be the lowest fraction overall.
Now let's look at the absolute values:
- Absolute value of \(-\frac{1}{8}\) is \(\frac{1}{8}\).
- Absolute value of \(-\frac{5}{8}\) is \(\frac{5}{8}\).
- Absolute value of \(-\frac{7}{8}\) is \(\frac{7}{8}\).
- Absolute value of \(-\frac{3}{8}\) is \(\frac{3}{8}\).
Ordering these absolute values from smallest to largest:
- \(\frac{1}{8}\)
- \(\frac{3}{8}\)
- \(\frac{5}{8}\)
- \(\frac{7}{8}\)
Since \(-\frac{7}{8}\) has the highest absolute value, it is the lowest fraction. Therefore, the fraction with the lowest value is:
\[ -\frac{7}{8} \]
