Answer 1

Ответ:

$a) \frac{3}{14} :\frac{5}{17} =\frac{3}{14} *\frac{17}{5} =\frac{51}{70}$

$b) \frac{2}{11} :\frac{9}{44} =\frac{2}{11} *\frac{44}{9} =\frac{8}{9}$

$c) \frac{8}{27} :\frac{7}{9} :\frac{11}{7} \\\\\\\frac{8}{27} :\frac{7}{9} =\frac{8}{27} *\frac{9}{7} =\frac{8}{21} \\\\2) \frac{8}{21}:\frac{11}{7} =\frac{8}{21} *\frac{11}{7}=\frac{88}{147}$
