\(=\dfrac{19}{8}.\dfrac{16}{9}+\dfrac{19}{8}.\dfrac{2}{9}-\dfrac{19}{8}.1=\dfrac{19}{8}.\left(\dfrac{16}{9}+\dfrac{2}{9}-1\right)\)

\(=\dfrac{19}{8}.1=\dfrac{19}{8}\)

\(\dfrac{19}{8}\times\dfrac{16}{9}+\dfrac{19}{8}\times\dfrac{2}{9}-\dfrac{19}{8}\)

\(=\dfrac{19}{8}\times\left(\dfrac{16}{9}+\dfrac{2}{9}-1\right)\)

\(=\dfrac{19}{8}\times1\)

\(=\dfrac{19}{8}\)
