Question

(2 целых 3 восьмих-1 целая 5 шестих):(-1 целая 5 десятых)

Answer 1

$(2 \frac{3}{8} - 1 \frac{5}{6} ) \div ( - 1.5) = ( \frac{19}{8} - \frac{11}{6} ) \div ( - \frac{3}{2} ) = \frac{13}{24} \div ( - \frac{3}{2} ) = - \frac{13}{24} \times \frac{2}{3} = - \frac{13}{12} \times \frac{1}{3} = - \frac{13}{36}$
