Question

2/3•(1-5/6) :1/3 помогите пожалуйста

Answer 1

Объяснение:

$\frac{2}{3} \times (1 - \frac{5}{6}) \div \frac{1}{3} = \frac{\frac{2}{3}\left(\frac{6}{6}-\frac{5}{6}\right)}{\frac{1}{3}} =\frac{\frac{2}{3}\times \left(\frac{6-5}{6}\right)}{\frac{1}{3}} =\frac{\frac{2}{3}\times \left(\frac{1}{6}\right)}{\frac{1}{3}} =\frac{\frac{2\times 1}{3\times 6}}{\frac{1}{3}} =\frac{\frac{2}{18}}{\frac{1}{3}} =\frac{\frac{1}{9}}{\frac{1}{3}} =\frac{1}{9}\times 3 =\frac{3}{9} =\frac{1}{3}$

Answer 2

$\displaystyle \frac{2}{3} *(1-\frac{5}{6} ):\frac{1}{3} =\frac{2}{3} *(\frac{6-5}{6} )*\frac{1}{3} =\frac{2}{3} *\frac{1}{6} *\frac{3}{1} =\frac{6}{18} =\frac{1}{3} .$
