$4 \div (5 \frac{1}{3} + 2 \frac{2}{3} ) = 4 \div 8 = \frac{4}{8} = 0.5$

$( - 8 \frac{1}{12} + 6 \frac{1}{4} ) \times 3 = - 5 \frac{1}{2} = - 5.5$

$\frac{3}{7} \times ( - 4 \frac{2}{3} ) \div ( - \frac{1}{2} ) = 4$

$(3 \frac{2}{3} - 1 \frac{2}{7} \times 5 \frac{4}{9} ) \div ( - 2.5) = \frac{9}{50} = 0.18$

$\frac{9}{7} *\frac{49}{9} =7\\\frac{11}{3} -7=-\frac{10}{3} \\\\-\frac{10}{3} :-\frac{25}{10} =\frac{10}{3} :\frac{10}{25}=\frac{4}{3}= 1\frac{1}{3}$
