$\frac{4}{7} + \frac{4}{9} + \frac{3}{7} - \frac{13}{9}$
​

Answer 1

Answer:

$\red { \frac{4}{7} + \frac{4}{9} + \frac{3}{7} - \frac{13}{9}}\green {= 0}$

Step-by-step explanation:

$\frac{4}{7} + \frac{4}{9} + \frac{3}{7} - \frac{13}{9}$

$=\frac{4}{7} + \frac{3}{7} + \frac{4}{9} - \frac{13}{9}]$

$\pink {(commutative \: property )}$

$= \frac{( 4+3)}{7} + \frac{ (4-13)}{9}$

$= \frac{7}{7} + \frac{-9}{9}$

$= 1 + (-1) \\= 1-1\\= 0$

Therefore.,

$\red { \frac{4}{7} + \frac{4}{9} + \frac{3}{7} - \frac{13}{9}}\green {= 0}$

Answer 2

Step-by-step explanation:

Commutative property

4/7 + 4/9 + 3/7 + 13/9

= (4+3)/7 + (4+13)/9

= 7/7 + 17/9

= (63 + 119)/63

= 182/63
