Question

2/9 *7/13+-11/9* 7/13 +7/13

Answer 1

`2/9 xx7/13+(-11/9)xx 7/13 +7/13`

`=2/9 xx7/13+(-11/9)xx 7/13 +7/13 xx 1`

`= 7/13 xx ( 2/9 + (-11)/9 +1)`

`=7/13xx0`

`=0`

Answer 2

\(\dfrac{2}{9}\times\dfrac{7}{13}+\left(-\dfrac{11}{9}\right)\times\dfrac{7}{13}+\dfrac{7}{13}\)

\(=\dfrac{7}{13}\times\left(\dfrac{2}{9}+\dfrac{-11}{9}+1\right)\)

\(=\dfrac{7}{13}\times0\)

\(=0\)
