\(\dfrac{4}{5}\times\dfrac{16}{9}-\dfrac{7}{9}\times\dfrac{4}{5}-\dfrac{4}{5}\)
\(=\dfrac{4}{5}\times\left(\dfrac{16}{9}-\dfrac{7}{9}-1\right)\)
\(=\dfrac{4}{5}\times0\)
\(=0\)

4/5 x 16/9 - 7/9 x 4/5 - 4/5
= 4/5 x ( 16/9 - 7/9 - 1 )
= 4/5 x 0 = 0
=\(\dfrac{4}{5}\times\left(\dfrac{16}{9}-\dfrac{7}{9}-1\right)\)
=\(\dfrac{4}{5}\times0\) = 0
