=\(\dfrac{2}{3}\times\left(\dfrac{4}{9}+\dfrac{5}{9}\right)=\dfrac{2}{3}\times\dfrac{9}{9}=\dfrac{2}{3}\)
\(=\dfrac{2}{3}\times\left(\dfrac{4}{9}+\dfrac{5}{9}\right)\\ =\dfrac{2}{3}\times1=\dfrac{2}{3}\)
\(=\dfrac{2}{3}\left(\dfrac{4}{9}+\dfrac{5}{9}\right)=\dfrac{2}{3}\)
= 2/3x ( 4/9 + 5/9)
= 2/3 x
= 2/39/9= 2/3 x 1=2/3
= \(\dfrac{2}{3}\times\left(\dfrac{4}{9}+\dfrac{5}{9}\right)\)
\(=\dfrac{2}{3}\times1\)
\(=\dfrac{2}{3}\)
\(\dfrac{2}{3}\times\dfrac{4}{9}+\dfrac{2}{3}\times\dfrac{5}{9}\)
\(=\dfrac{2}{3}\times\left(\dfrac{4}{9}+\dfrac{5}{9}\right)\)
\(=\dfrac{2}{3}\times1\)
\(=\dfrac{2}{3}\)
