The correct Answer is:
To arrange the fractions \( \frac{4}{5}, \frac{7}{8}, \frac{6}{7}, \frac{5}{6} \) in ascending order, we will first convert each fraction to a decimal form for easier comparison. ### Step 1: Convert each fraction to decimal 1. **Convert \( \frac{4}{5} \)**: \[ \frac{4}{5} = 0.8 \] 2. **Convert \( \frac{7}{8} \)**: \[ \frac{7}{8} = 0.875 \] 3. **Convert \( \frac{6}{7} \)**: \[ \frac{6}{7} \approx 0.8571 \quad (\text{approximately}) \] 4. **Convert \( \frac{5}{6} \)**: \[ \frac{5}{6} \approx 0.8333 \quad (\text{approximately}) \] ### Step 2: List the decimal values Now we have the following decimal values: - \( \frac{4}{5} = 0.8 \) - \( \frac{7}{8} = 0.875 \) - \( \frac{6}{7} \approx 0.8571 \) - \( \frac{5}{6} \approx 0.8333 \) ### Step 3: Compare the decimal values Now we can compare the decimal values: - \( 0.8 \) (from \( \frac{4}{5} \)) - \( 0.8333 \) (from \( \frac{5}{6} \)) - \( 0.8571 \) (from \( \frac{6}{7} \)) - \( 0.875 \) (from \( \frac{7}{8} \)) ### Step 4: Arrange in ascending order From the comparisons, we can see that: 1. \( 0.8 \) (which is \( \frac{4}{5} \)) 2. \( 0.8333 \) (which is \( \frac{5}{6} \)) 3. \( 0.8571 \) (which is \( \frac{6}{7} \)) 4. \( 0.875 \) (which is \( \frac{7}{8} \)) Thus, the fractions in ascending order are: \[ \frac{4}{5}, \frac{5}{6}, \frac{6}{7}, \frac{7}{8} \] ### Final Answer: The fractions arranged in ascending order are: \[ \frac{4}{5} < \frac{5}{6} < \frac{6}{7} < \frac{7}{8} \]
