Question

Plz tell me use distributive property of multiplication of rational numbers over their addition and simplify

Answer 1

Distributive property of multiplication:-

$a(b + c) = ab + ac$

Solution:-

$\: \: \: 1 \frac{1}{7} ( \frac{6}{7} + \frac{ - 3}{5} ) \\ \\ = \frac{8}{7} ( \frac{6}{7} - \frac{3}{5} ) \\ \\ = \frac{48}{49} - \frac{24}{35} \\ \\ = \frac{240 -168 }{245} \\ \\ = \frac{72}{245}$
