Question

3/7(-2/5)+(2/5)(1/3)(9/7)=0 how

Answer 1

3/2(-2/5)+(2/5)(1/3)(9/7))=0

It have to be proved.

$\frac{3}{2} \times ( \frac{ - 2}{5} + \frac{2}{5} \times \frac{1}{3} \times \frac{9}{7} )$

By cancelling 9 by 3

then,

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

then,

$\frac{3}{2} \times ( \frac{ - 2}{5} + \frac{6}{35} )$

then,

$\frac{3}{2} \times ( \frac{ - 14}{35} + \frac{6}{35} )$

then,

$\frac{3}{2} \times ( \frac{ - 8}{35} )$

then,

${3}( \frac{ - 4}{35} )$

then,

$\frac{ - 12}{35}$

It was step by step method.. By this we reach to an end.. By completely solving the problem.
