Step-by-step explanation:

Question:

Using appropriate property Find the value of:

$- \frac{ 2}{3} \times \frac{5}{6} - \frac{2}{3} \times \frac{4}{7}$

Solution:

Using property: Distribution Law

a(b + c) = ab + ac

$- \frac{ 2}{3} \times \frac{5}{6} - \frac{2}{3} \times \frac{4}{7} \\ = - \frac{2}{3} {\huge(} \frac{5}{6} + \frac{4}{7} \huge) \\ = - \frac{2}{3} \times {\huge(} \frac{35 + 24}{42} \huge) \\ = - \frac{ \cancel2}{3} \times \frac{59}{ \cancel{42}}_{21} \\ = \pink{ - \frac{59}{63} }$
