$\displaystyle (1\frac{2}{3}+2\frac{4}{9}):(4\frac{26}{27}-2\frac{2}{9})=((1+2)+(\frac{2}{3}+\frac{4}{9})):(\frac{134}{27}-\frac{20}{9})=(3+\frac{10}{9}):\frac{74}{27}=\\ \\ (3+1\frac{1}{9})* \frac{27}{74}=(3+1+\frac{1}{9})*\frac{27}{74}=(4+\frac{1}{9})*\frac{27}{74}=4\frac{1}{9}*\frac{27}{74}=\frac{37}{9}*\frac{27}{74}=\frac{3}{2}=1\frac{1}{2}=1,5$
