Question

-3/7:(1 1/14)
/ это дробь

Answer 1

$-\dfrac{3}{7} : 1\dfrac{1}{14} = -\dfrac{3}{7} : \dfrac{15}{14}=-\dfrac{3}{7} *\dfrac{14}{15}=-\dfrac{1}{1} *\dfrac{2}{5}=-\dfrac{2}{5}$

Answer 2

$- \frac{3}{7} \div (1 \frac{1}{14} ) = - \frac{3}{7} \div 1 \frac{1}{14} = - \frac{3}{7} \div \frac{15}{14} = \\ \\ - \frac{3}{7} \times \frac{14}{15} = - \frac{3 \times 14}{7 \times 15} = - \frac{42}{105} = - \frac{2 {}^{(2} }{5} = - \frac{4}{10} = - 0.4$
