Answer 1

Ответ:

$\frac{8}{5} = 1.6$

Пошаговое объяснение:

$10 - 3 \frac { 3 } { 4 } \cdot ( 2 \frac { 1 } { 3 } + 1 \frac { 2 } { 5 } ) : 1 \frac { 5 } { 9 } + \frac { 3 } { 5 }$

$10-\frac{\frac{12+3}{4}\left(\frac{2\times 3+1}{3}+\frac{1\times 5+2}{5}\right)}{\frac{1\times 9+5}{9}}+\frac{3}{5}$

$10-\frac{\frac{15}{4}\left(\frac{2\times 3+1}{3}+\frac{1\times 5+2}{5}\right)}{\frac{1\times 9+5}{9}}+\frac{3}{5}$

$10-\frac{\frac{15}{4}\left(\frac{6+1}{3}+\frac{1\times 5+2}{5}\right)}{\frac{1\times 9+5}{9}}+\frac{3}{5}$

$10-\frac{\frac{15}{4}\left(\frac{7}{3}+\frac{1\times 5+2}{5}\right)}{\frac{1\times 9+5}{9}}+\frac{3}{5}$

$10-\frac{\frac{15}{4}\left(\frac{7}{3}+\frac{7}{5}\right)}{\frac{1\times 9+5}{9}}+\frac{3}{5}$

$10-\frac{\frac{15}{4}\times \left(\frac{35+21}{15}\right)}{\frac{1\times 9+5}{9}}+\frac{3}{5}$

$10-\frac{\frac{15\times 56}{4\times 15}}{\frac{1\times 9+5}{9}}+\frac{3}{5}$

$10-\frac{\frac{56}{4}}{\frac{1\times 9+5}{9}}+\frac{3}{5}$

$10-\frac{14}{\frac{9+5}{9}}+\frac{3}{5}$

$10-\frac{14}{\frac{14}{9}}+\frac{3}{5}$

$10-14\times \left(\frac{9}{14}\right)+\frac{3}{5}$

$10-9+\frac{3}{5}$

$1+\frac{3}{5}$

$\frac{5+3}{5}$

$\frac{8}{5}$
