Question

2/3 ∶(-2)= ( -5/6):(-5/12)= 4 : (- 1/2)= (-4 2/3)∶ 2/9 =

Answer 1

Ответ:

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

$( - \frac{5}{6}) \div ( - \frac{5}{12} ) = \frac{5 \times 12}{6 \times 5} = 2$

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