Question

solving by using appropriate properties 3/7 × -1/2 - 4/7 × 2 + 3/7 × (-6)​

Answer 1

Answer

$\frac{3}{7} \times \frac{ - 1}{2} \times \frac{ - 4}{7} \times 2 + \frac{3}{7} \times ( - 6) \\ \frac{3 \times ( - 1)}{7 \times 2} \times \frac{ - 4 \times 2}{7} + \frac{3}{7} \times ( - 6) \\ \frac{ - 3}{14} \times \frac{ - 6}{7} + \frac{3}{7} \times ( - 6) \\ \frac{ - 3 \times - 6}{14 \times 7} + \frac{3}{7} \times ( - 6) \\ \frac{18}{98} + \frac{3}{7} \times ( - 6) \\ \frac{9}{49} + \frac{3}{7} \times ( - 6) \\ \frac{(9 \times 7) + (49 \times 3)}{49 \times 7} \times ( - 6) \\ \frac{63 + 147}{343} \times ( - 6) \\ \frac{210}{343} \times ( - 6) \\ \frac{210 \times ( - 6)}{343} \\ \frac{ - 1260}{343}$
