Answer 1

$1)2 \frac{1}{3} - 3.8 = \frac{7}{3} - 3 \frac{8}{10} = \frac{7}{3} - \frac{38}{10} = \\ = \frac{70 - 114}{30} = - \frac{44}{30} = - \frac{22}{15}$

$2) - \frac{22}{15} \times ( - 1 \frac{7}{8} ) = \frac{22}{15} \times \frac{15}{8} = \frac{22}{8} = \frac{11}{4}$

$3)4 \frac{1}{6} \div ( - 1 \frac{2}{3} ) = \frac{25}{6} \div ( - \frac{5}{3} ) = - ( \frac{25}{6} \times \frac{3}{5} ) = - \frac{5}{2}$

$4) \frac{11}{4} + ( - \frac{5}{2} ) = \frac{11}{4} - \frac{10}{4} = \frac{1}{4}$
