15*(1/5 2 - 8*1/5)

To solve the expression \( 15 \left( \frac{1}{5} 2 - 8 \cdot \frac{1}{5} \right) \), we can follow these steps: 1. Calculate \( \frac{1}{5} \cdot 2 \): \[ \frac{1}{5} \cdot 2 = \frac{2}{5} \] 2. Calculate \( 8 \cdot \frac{1}{5} \): \[ 8 \cdot \frac{1}{5} = \frac{8}{5} \] 3. Now substitute these values back into the expression: \[ 15 \left( \frac{2}{5} - \frac{8}{5} \right) \] 4. Subtract the fractions: \[ \frac{2}{5} - \frac{8}{5} = \frac{2 - 8}{5} = \frac{-6}{5} \] 5. Now multiply by 15: \[ 15 \left( \frac{-6}{5} \right) = 15 \cdot \frac{-6}{5} = \frac{15 \cdot -6}{5} = \frac{-90}{5} = -18 \] Therefore, the final result is: \[ \boxed{-18} \]
