Răspuns:

ex. 1

$-\frac{12}{18} = -\frac{2}{3}\\\\ \frac{17}{5} = 3\frac{2}{5} \\\\-1\frac{4}{5} = -\frac{27}{15} \\\\\frac{8}{24} = \frac{1}{3}$

ex.2

a) =

b) =

c) >
ex.3

a) $6\frac{5}{8}^{(3} + 1\frac{7}{12}^{(2} =6\frac{15}{24} + 1\frac{14}{24} = 7\frac{29}{24} = 8\frac{5}{24}$
b) $-\frac{7}{16}^{(3} + \frac{5}{24}^{(2} = -\frac{21}{48} +\frac{10}{48} = - \frac{11}{48}$
c) $(-\frac{5}{16} )$ ° $\frac{8}{25} =$ $- \frac{40}{400} ^{(40} = -\frac{1}{10}$

d) $-\frac{5}{7} : (-1\frac{1}{14} ) = -\frac{5}{7}$ ° $(-\frac{14}{15} ) = \frac{70}{105}^{(5} = \frac{14}{21}^{(7}= \frac{2}{3}$
