Question

 `5/9 . 7/13 + 5/9 . 13 - 5/9 . 3/13`

Answer 1

\(\dfrac{5}{9}\cdot\dfrac{7}{13}+\dfrac{5}{9}\cdot13-\dfrac{5}{9}\cdot\dfrac{3}{13}\)

\(=\dfrac{5}{9}\cdot\left(\dfrac{7}{13}-\dfrac{3}{13}+13\right)\)

\(=\dfrac{5}{9}\cdot\left(\dfrac{4}{13}+13\right)\)

\(=\dfrac{5}{9}\cdot\dfrac{173}{13}\)

\(=\dfrac{865}{117}\)

Answer 2

=5/9(7/13+13-3/13)

=5/9*(13+4/13)

=5/9*173/13=865/117
