= $\left(\frac{4}{7}\div\frac{3}{5}\right)+\left(\frac{6}{5}\times\frac{2}{9}\right)$

= $\left(\frac{4}{7}\times\frac{5}{3}\right)+\left(\frac{12}{45}\right)$

= $\frac{20}{21}+\frac{12}{45}$ ---> KPK dari 21 dan 45 = 315

= $\frac{20\times15}{21\times15}+\frac{12\times7}{45\times7}$

= $\frac{300}{315}+\frac{84}{315}$

= $\frac{384}{315}$

= $1\frac{69}{315}$

= $1\frac{69\ \div3}{315\div3}=\ 1\frac{23}{105}$
