Question

Задание№5Выполните действия (-3/4-1/6):(-1 3/8)​

Answer 1

Ответ:

$( - \frac{3}{4} - \frac{1}{6} ) \div ( - 1 \frac{3}{8} )$

$- \frac{3}{4} - \frac{1}{6} = - \frac{9}{12} - \frac{2}{12} = - \frac{11}{12}$

$- \frac{11}{12} \div ( - 1 \frac{3}{8} ) = \frac{11}{12} \div 1 \frac{3}{8} = \frac{11}{12} \div \frac{11}{8} = \frac{11}{12} \times \frac{8}{11} = \frac{1}{3} \times \frac{2}{1} = \frac{2}{3}$

Ответ:$\frac{2}{3}$
