Question

Найдите х
7/8:х=1/4
х:1 2/3=1/3
1 1/3х=3/5
2 2/3:х=3 3/5

Answer 1

$\frac{7}{8} :x=\frac{1}{4}$

$x=\frac{7}{8} :\frac{1}{4}$

$x=\frac{7}{8} *\frac{4}{1}$

$x=\frac{7}{2}$

$x=3\frac{1}{2}$

$x:1\frac{2}{3} =\frac{1}{3}$

$x =\frac{1}{3}* 1\frac{2}{3}$

$x =\frac{1}{3}* \frac{5}{3}$

$x =\frac{5}{9}$

$1\frac{1}{3}x=\frac{3}{5}$

$x=\frac{3}{5} : 1\frac{1}{3}$

$x=\frac{3}{5} :\frac{4}{3}$

$x=\frac{3}{5} *\frac{3}{4}$

$x=\frac{9}{20}$

$2\frac{2}{3} :x=3\frac{3}{5}$

$\frac{8}{3} :x=\frac{18}{5}$

$x=\frac{8}{3} :\frac{18}{5}$

$x=\frac{8}{3} *\frac{5}{18}$

$x=\frac{4}{3} *\frac{5}{9}$

$x=\frac{20}{27}$
