[tex]1.6 + 4 \frac{3}{5} \div 2.3 - 2 \frac{2}{5} = 1.6 + 4.6 \div 2.3 - 2.4 = 1.6 + 2 - 2.2 = 1.6 + 0.2 = 1.8[/tex]

[tex]( \frac{5}{6} + \frac{1}{3} ) \div (2 \frac{2}{3} - 1.75) = ( \frac{5}{6} + \frac{1}{3} ) \div (2 \frac{2}{3} - 1 \frac{3}{4} ) = ( \frac{5}{6} + \frac{2}{6} ) \div (2 \frac{8}{12} - 1 \frac{9}{12} ) = \frac{7}{6} \div (1 \frac{20}{12} - 1 \frac{9}{12} ) = \frac{7}{6} \div \frac{11}{12} = \frac{7}{6} \times \frac{12}{11} = \frac{14}{11} = 1 \frac{3}{11} [/tex]
