Question

2) (3 11/27 - 2 17/18) : 1 23/27

Answer 1

Ответ:

$0,25$

Пошаговое объяснение:

$(3\frac{11}{27}-2\frac{17}{18}):1\frac{23}{27}=(\frac{3*27+11}{27}-\frac{2*18+17}{18}):\frac{1*27+23}{27}=(\frac{81+11}{27}-\frac{36+17}{18}):\frac{27+23}{27}=$

$=(\frac{92}{27}-\frac{53}{18}):\frac{50}{27}=(\frac{92}{27}-\frac{53}{18})*\frac{27}{50}=\frac{92}{27}*\frac{27}{50}-\frac{53}{18}*\frac{27}{50}=\frac{92*27}{27*50}-\frac{53*9*3}{9*2*50}=$

$=\frac{92}{50}-\frac{53*3}{2*50}=\frac{2*92}{2*50}-\frac{53*3}{2*50}=\frac{2*92-53*3}{2*50}=\frac{184-159}{100}=\frac{180+4-150-9}{100}=\frac{30-5}{100}=$

$=\frac{25}{100}=0,25;$
