24. \( \begin{array}{r}\frac{3}{4} \\ -\frac{1}{8} \\ \hline\end{array} \)

To solve the problem, we need to perform the subtraction of the two fractions: \( \frac{3}{4} - \frac{1}{8} \). ### Step 1: Find a common denominator The denominators of the fractions are 4 and 8. The least common denominator (LCD) is 8. ### Step 2: Convert the fractions We need to convert \( \frac{3}{4} \) to a fraction with a denominator of 8. We do this by multiplying both the numerator and the denominator by 2: \[ \frac{3}{4} = \frac{3 \times 2}{4 \times 2} = \frac{6}{8} \] Now we can rewrite the subtraction: \[ \frac{6}{8} - \frac{1}{8} \] ### Step 3: Perform the subtraction Now that both fractions have the same denominator, we can subtract the numerators: \[ \frac{6 - 1}{8} = \frac{5}{8} \] ### Final Answer Thus, the result of \( \frac{3}{4} - \frac{1}{8} \) is: \[ \frac{5}{8} \]
