$\large\underbrace{\color{green}\bf\: Solution\:}$

$\longrightarrow$ $\dfrac{2}{3} \times \dfrac{1}{5} + \dfrac{4}{7} - \dfrac{2}{9} \times \dfrac{1}{5}$

$\Rightarrow$ $\dfrac{2}{15} + \dfrac{4}{7} - \dfrac{2}{45}$

$\Rightarrow$ $\dfrac{14 + 60}{105} - \dfrac{2}{45}$

$\Rightarrow$ $\dfrac{74}{105} - \dfrac{2}{45}$

$\Rightarrow$ $\dfrac{222 - 14}{315}$

$\Rightarrow$ $\dfrac{208}{315}$

$\therefore$ $The\: answer\: of\: this\: question\: is\: \dfrac{208}{315}$
