Answer 2

Răspuns:

$a)\:\frac{(\frac{11}{8}+\frac{1}{6}):\frac{37}{5}}{(\frac{11}{8}-\frac{3}{4}):\frac{1}{2}}=\frac{\frac{\not37}{24}\times\frac{5}{\not37}}{\frac{5}{8}\times2}=\frac{\frac{5}{24}}{\frac{5}{4}}=\frac{5}{24}:\frac{5}{4}=\frac{\not5}{24}\times\frac{4}{\not5}=\frac{4}{24}^{(4}=\bf\red{\frac{1}{6} }$

$b)\frac{(\frac{11}{24}+\frac{11}{36}):\frac{11}{6}}{(\frac{11}{6}-\frac{5}{9}):\frac{23}{5}}=\frac{\frac{\not55}{\not72}\times\frac{\not6}{\not11}}{\frac{\not23}{18}\times\frac{5}{\not23}}=\frac{\frac{5}{12}}{\frac{1}{18}\times5}=\frac{\frac{5}{12}}{\frac{5}{18}}=\frac{5}{12}:\frac{5}{18}=\frac{\not5}{12}\times\frac{18}{\not5}=\frac{18}{12}^{(6} =\bf\green{\frac{3}{2}}$
