Question

5/9.-7/13+5/9.-9/13+5/9-3/13

Answer 1

\(-\dfrac{29}{39}\)

Answer 2

\(\dfrac{5}{9}\times\dfrac{-7}{13}+\dfrac{5}{9}\times\dfrac{-9}{13}+\dfrac{5}{9}-\dfrac{3}{13}=-\dfrac{29}{39}\)

 

Answer 3

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

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

\(=\dfrac{5}{9}.\dfrac{-19}{13}\)

\(=\dfrac{-95}{117}\)
