Question

using suitable property find
4/7 + (-4/9)+3/7+(-3/9)​

Answer 1

$\frac{4}{7} + \frac{ - 4}{9} + \frac{3}{7} + \frac{ - 3}{9}$

We will bring the fractions with the same denominators together.

$( \frac{4}{7} + \frac{3}{7} ) + ( \frac{ - 4}{9} - \frac{3}{9} ) \\ = \frac{7}{7} + \frac{ - 7}{9} \\ = 1 - \frac{7}{9} \\ = \frac{9 - 7}{9} \\ = \frac{2}{9}$
