Answer 1

a) $2: \frac{1}{7} = \frac{2}{1} * \frac{7}{1} =14$
б)$8: \frac{3}{4} = \frac{8}{1} * \frac{4}{3} = \frac{32}{3} =10 \frac{2}{3}$
в)$\frac{10}{21} :5= \frac{10}{21} * \frac{1}{5} = \frac{2}{21}$
г)$\frac{2}{3} :4= \frac{2}{3}* \frac{1}{4}= \frac{1}{6}$

Answer 2

 а) 2:1/7=14
   14:2/1=7/1

б) 8:3/4=10 2/3
    8/15*20/1=10 2/3

в) 10/21:5=2/21
    4/21*1/2=2/21


г)2/3:4=1/6
   1/2*1/3=1/6
