Question

verify -2/3*(-5/4+4/7)=-2/3*-5/7+-3/2*-5​

Answer 1

Answer:

$\frac{ - 2}{3} \times ( \frac{ - 5}{4} + \frac{4}{7} ) = \frac{ - 2}{3 } \times \frac{ - 5}{7} + \frac{ - 3}{2} \times \frac{ - 5}{1}$

$\frac{ - 2}{3} \times ( \frac{ - 5 + 4}{28} )= \frac{ 10}{21} + \frac{15}{2}$

$\frac{ - 2}{3} \times \frac{ - 1}{28} = \frac{ 10 + 15}{42}$

$\frac{2}{84} = \frac{25}{42}$

Therefore, it is not equal
