To compute \( \frac{5}{17} \cdot 3 \frac{6}{15}-\frac{4}{5} \), we first convert the mixed number \( 3 \frac{6}{15} \) into an improper fraction. 1. Convert \( 3 \frac{6}{15} \): \[ 3 \frac{6}{15} = \frac{3 \cdot 15 + 6}{15} = \frac{45 + 6}{15} = \frac{51}{15} \] 2. Now, simplify \( \frac{51}{15} \): \[ \frac{51}{15} = \frac{17}{5} \text{ (since both 51 and 15 are divisible by 3)} \] 3. Next, compute \( \frac{5}{17} \cdot \frac{17}{5} \): \[ \frac{5}{17} \cdot \frac{17}{5} = \frac{5 \cdot 17}{17 \cdot 5} = 1 \] 4. Now, subtract \( \frac{4}{5} \) from \( 1 \): \[ 1 - \frac{4}{5} = \frac{5}{5} - \frac{4}{5} = \frac{1}{5} \] The final result is: \[ \frac{1}{5} \]
