Ответ:

1) $( \frac{4}{9} - \frac{11}{15} + \frac{2}{3}) \div 3 \frac{2}{5} + \frac{2}{9} = \frac{184}{675}$

2) $5 \div ( - 1.25) + 2.8 \times \frac{1}{7} + \frac{1}{3} = - \frac{49}{15}$

3)$(4 \frac{2}{7} \div 3 \frac{3}{14} - 8 + 4 \frac{6}{11}) \times 3 = - \frac{5091}{539}$

4) $9.8 \div (10 - 3 \frac{7}{15}) \times 1 \frac{1}{27} = \frac{1}{18}$
