Odpowiedź:
a) [tex]\frac{4}{3}x + \frac{5}{8}x = (\frac{4}{3} + \frac{5}{8})x = (\frac{32}{24} +\frac{15}{24})x= \frac{47}{24}x=1\frac{23}{24}x\\[/tex]
b) [tex]1,2x + \frac{2}{3}x = (1\frac{2}{10} + \frac{2}{3})x = ( 1 \frac{6}{30} + \frac{20}{30})x = 1\frac{26}{30}x= 1\frac{13}{15}[/tex]x
c)[tex]\frac{1}{4}x + \frac{5}{6}x -\frac{1}{2}x = (\frac{3}{12}+\frac{10}{12}-\frac{6}{12})x=(\frac{13}{12} - \frac{6}{12})x=\frac{7}{12}x[/tex]
d) [tex]\frac{3}{7}x-0,2x+x=(\frac{3}{7}-\frac{2}{10}+1)x=(\frac{30}{70}-\frac{14}{70}+1)x=\frac{16}{70}x=\frac{8}{35}[/tex]x
