((3frac (11)/(27)-2(17)/(18)):1(23)/(27)-3(3)/(5):8)((43-42(2)/(3)):(2)/(3))+2,5

Давайте разберем выражение шаг за шагом:<br /><br />1. Вычислим выражение в скобках:<br />$3\frac {11}{27} - 2\frac {17}{18} = \frac{92}{27} - \frac{53}{18} = \frac{184}{54} - \frac{141}{54} = \frac{43}{54}$<br /><br />$1\frac {23}{27} = \frac{40}{27}$<br /><br />$3\frac {3}{5} = \frac{18}{5}$<br /><br />2. Теперь подставим значения в исходное выражение:<br />$\frac {(3\frac {11}{27}-2\frac {17}{18}):1\frac {23}{27}-3\frac {3}{5}:8}{(43-42\frac {2}{3}):\frac {2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />3. Выполним деления и сложим результаты:<br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27} - \frac{18}{5}:\frac{8}}{(43-\frac{128}{3}):\frac{2}{3}}+2,5$<br /><br />$\frac {\frac{43}{54}:\frac{40}{27
