Question

-4/9.7/15+4/-9.8/15

 

Answer 1

\(\dfrac{-4}{9}.\dfrac{7}{15}+\dfrac{4}{-9}.\dfrac{8}{15}\)

=\(\dfrac{-4}{9}.\left(\dfrac{7}{15}+\dfrac{8}{15}\right)\)

=\(\dfrac{-4}{9}.1\)=\(\dfrac{-4}{9}\)

Answer 2

\(\dfrac{-4}{9}.\dfrac{7}{15}+\dfrac{4}{-9}.\dfrac{8}{15}\) 

\(=\dfrac{-4}{9}.\dfrac{7}{15}+\dfrac{-4}{9}.\dfrac{8}{15}\) 

\(=\dfrac{-4}{9}.\left(\dfrac{7}{15}+\dfrac{8}{15}\right)\) 

\(=\dfrac{-4}{9}.1\) 

\(=\dfrac{-4}{9}\)
