h) Evaluate \( \frac{7}{8}-\frac{1}{4} \)

To evaluate \( \frac{7}{8} - \frac{1}{4} \), first, we need a common denominator. The least common denominator of 8 and 4 is 8. Next, convert \( \frac{1}{4} \) to have a denominator of 8: \[ \frac{1}{4} = \frac{1 \times 2}{4 \times 2} = \frac{2}{8} \] Now, substitute this back into the original expression: \[ \frac{7}{8} - \frac{2}{8} = \frac{7 - 2}{8} = \frac{5}{8} \] So, the result of \( \frac{7}{8} - \frac{1}{4} \) is \( \frac{5}{8} \).
