Question

Приклад по діях 6/7 :(1/14-5/6)

Answer 1

$\frac{6}{7} : (\frac{1}{14} -\frac{5}{6} )$

1)$\frac{1}{14} -\frac{5}{6}$ (домножаем 1-ю дробь на 3, 2-ю на 7) = $\frac{3}{42} - \frac{35}{42} = -\frac{32}{42} = - \frac{16}{21}$

2) $\frac{6}{7} : (-\frac{16}{21} )=-\frac{6*21}{7*16}= -\frac{3*3}{1*8} = -\frac{9}{8} =-1\frac{1}{8}$

Ответ: $-1\frac{1}{8}$
