Question

Simplify using properties: 3/7 * (-5/6) + 2/3 - 5/6 * 5/7

Answer 1

Answer:

$\bold{ \frac{ - 2}{7} }$

Step-by-step explanation:

$\bold{ \frac{3}{7} \times ( \frac{ - 5}{6} ) + \frac{2}{3} - \frac{5}{6} \times \frac{5}{7} } \\ \bold{ \frac{ - 15}{42} + \frac{2}{3} - \frac{25}{42} } \\ \bold{ \frac{ - 15 + 28 - 25}{42} } \\ \bold{ - \frac{12}{42} } \\ \bold{ \frac{ - 2}{7}ans }$
