Answer 1

Ответ:

Пошаговое объяснение:

$3\frac{1}{3} :\frac{2}{3} *\frac{1}{5}$

$1)3\frac{1}{3} :\frac{2}{3} =\frac{10}{3}:\frac{2}{3}=\frac{10}{3} *\frac{3}{2} =\frac{5}{1}$

$2)\frac{5}{1} *\frac{1}{5} =\frac{1}{1} =1$

$\frac{4}{5} *2\frac{1}{2} :6$

$1)\frac{4}{5}*2\frac{1}{2} =\frac{4}{5} *\frac{5}{2} =\frac{2}{1}$

$2)\frac{2}{1} :6=\frac{2}{1} :\frac{6}{1} =\frac{2}{1} *\frac{1}{6} =\frac{1}{3}$

$3\frac{1}{5}*\frac{5}{8}:\frac{2}{7}$

$1)3\frac{1}{5} *\frac{5}{8} =\frac{16}{5} *\frac{5}{8}=\frac{2}{1}$

$2)\frac{2}{1} :\frac{2}{7} =\frac{2}{1}*\frac{7}{2} =\frac{7}{1} =7$

$26:3\frac{1}{4} *\frac{1}{16}$

$1)26:3\frac{1}{4} =\frac{26}{1}:\frac{13}{4}=\frac{26}{1}*\frac{4}{13}=\frac{8}{1}$

$2)\frac{8}{1} *\frac{1}{16} =\frac{1}{2}$

$4\frac{1}{8}*\frac{6}{11}:2\frac{1}{4}$

$1)4\frac{1}{8} *\frac{6}{11} =\frac{33}{8}*\frac{6}{11} =\frac{9}{4}$

$2)\frac{9}{4} :2\frac{1}{4} =\frac{9}{4} :\frac{9}{4} =1$

$1\frac{1}{7} *\frac{3}{4} :\frac{3}{10}$

$1)1\frac{1}{7} *\frac{3}{4} =\frac{8}{7}*\frac{3}{4}=\frac{6}{7}$

$2)\frac{6}{7} :\frac{3}{10} =\frac{6}{7} *\frac{10}{3} =\frac{20}{7} =2\frac{6}{7}$
