حاصل تقسیم های زیر را حساب کنید.

پاسخ

$$
-\frac{8}{9} \div (-8) = -\frac{8}{9} \times (-\frac{1}{8}) = +\frac{1}{9} \\[2ex]
-\frac{4}{7} \div (-\frac{5}{7}) = -\frac{4}{7} \times (-\frac{7}{5}) = +\frac{4}{5}\\[2ex]
-\frac{3}{8} \div (-\frac{3}{8}) = -\frac{3}{8} \times (-\frac{8}{3}) = +1\\[2ex]
1 \div (-\frac{2}{3}) = \frac{1}{1} \times (-\frac{3}{2}) = -\frac{3}{2}\\[2ex]
(+0.4) \div (-5) = \frac{4}{10} \times (-\frac{1}{5}) = -\frac{2}{25}\\[2ex]
-0.8 \div 4 = -\frac{8}{10} \times \frac{1}{4} = - \frac{1}{5}
$$
