Answer 1

$(1 frac{3}{5} + 1.8) times frac{1}{2} = \ = (1.6 + 1.8) div 2 = \ = 3.4 div 2 = 1.7$
$(5.4 - 2 frac{1}{3} ) div 7 frac{2}{3} = \ = (5 frac{2}{5} - 2 frac{1}{3} ) div frac{23}{3} = \ = ((5 - 2) + ( frac{2}{5} - frac{1}{3} )) times frac{3}{23} = \ = (3 + frac{1}{15} )times frac{3}{23} = \ = frac{46}{15} times frac{3}{23} = frac{2}{5} = 0.4$
