Answer 1

Odpowiedź:

a) [tex]1\frac{3}{5} - 2\frac{1}{6} = 1\frac{18}{30} - 2\frac{5}{30} = -\frac{17}{30}[/tex]

b) [tex]3\frac{3}{8} - 2\frac{5}{6} = 3\frac{9}{24} + 2 \frac{20}{24} = 6\frac{5}{24}[/tex]

c) [tex]\frac{1}{2} - (-\frac{1}{6} - \frac{1}{3} ) = \frac{3}{6} - ( -\frac{1}{6} - \frac{2}{3} ) = \frac{3}{6} + \frac{3}{6} = 1[/tex]

d) [tex]\frac{7}{6} + (-\frac{5}{4} -\frac{4}{3} ) = \frac{14}{12} + (-\frac{15}{12} -\frac{16}{12} )=\frac{14}{12} - \frac{31}{12} = -\frac{17}{12}[/tex]

e) [tex]-(-2\frac{2}{3} )+\frac{7}{15} = 2\frac{10}{15} +\frac{7}{15} = 3\frac{2}{15}[/tex]

f) [tex]-1\frac{9}{16} + \frac{11}{12}= -1\frac{27}{48} + \frac{44}{48} = -\frac{31}{48}[/tex]
