Answer 1

Răspuns:

• a)

$(\frac{2}{5} + \frac{3}{4} ) : \frac{23}{4}$

$(\frac{8+15}{20} * \frac{4}{23}$

$\frac{23}{20} * \frac{4}{23}$

$\frac{1}{5}$

• b)

$\frac{11}{2} : (\frac{3}{4} + \frac{5}{8} )$

$\frac{11}{2} : (\frac{6+5}{8} )$

$\frac{11}{2} * \frac{8}{11} = \frac{8}{2} = 4$

• c)

$(\frac{5}{4} + \frac{7}{6} ): \frac{29}{6}$

$(\frac{30+28}{24} )*\frac{6}{29}$

$\frac{58}{24} *\frac{6}{29} = \frac{12}{24} = \frac{1}{2}$

• d)

$\frac{17}{12} : ( \frac{5}{6} - \frac{1}{8} )$

$\frac{17}{12} : (\frac{40-6}{48 } )$

$\frac{17}{12} * \frac{48}{34}$

$\frac{4}{2} = 2$
