Jawaban:

$c)1 \frac{2}{3} + 2,6 + \frac{4}{6} \\ = \frac{5}{3} + \frac{26}{10} + \frac{4}{6} \\ = \frac{50}{30} + \frac{78}{30} + \frac{20}{30} \\ = \frac{148}{30} \\ = \frac{74}{15} \\ = 4 \frac{14}{15}$

$d)2 \frac{5}{8} - 1 \frac{2}{6} \\ = \frac{21}{8} - \frac{8}{6} \\ = \frac{63}{24} - \frac{32}{24} \\ = \frac{31}{24} \\ = 1 \frac{7}{24}$

$e)5 \frac{3}{8} - 2 \frac{3}{4} - 3 \frac{1}{2} \\ = \frac{43}{8} - \frac{11}{4} - \frac{7}{2} \\ = \frac{43}{8} - \frac{22}{8} - \frac{28}{8} \\ = - \frac{7}{8}$

$f)0,218 + 2,76 \\ = \frac{218}{1.000} + \frac{276}{100} \\ = \frac{218}{1.000} + \frac{2.760}{1.000} \\ = \frac{2.978}{1.000} \\ = 2,978$

$9)1 \frac{5}{6} - 2 \frac{1}{3} - 2,1 \\ = \frac{11}{6} - \frac{7}{3} - \frac{21}{10} \\ = \frac{55}{30} - \frac{70}{30} - \frac{63}{30} \\ = - \frac{78}{30} \\ = - \frac{26}{10} \\ = - \frac{13}{5} \\ = - 2 \frac{3}{5}$

$h)2 \frac{3}{11} - \frac{5}{22} + \frac{1}{33} \\ = \frac{25}{11} - \frac{5}{22} + \frac{1}{33} \\ = \frac{150}{66} - \frac{15}{66} + \frac{2}{66} \\ = \frac{133}{66} \\ = 2 \frac{1}{66}$

$i) \frac{7}{10} - \frac{3}{100} +0,06 \\ = \frac{7}{10} - \frac{3}{ 100} + \frac{6}{100} \\ = \frac{70}{100} - \frac{3}{100} + \frac{6}{100} \\ = \frac{61}{100}$

$j)3 - 1\frac{3}{4} + 1,04 \\ = \frac{3}{1} - \frac{7}{4} + \frac{104}{100} \\ = \frac{300}{100} - \frac{175}{100} + \frac{104}{100} \\ = \frac{300}{100} - \frac{279}{100} \\ = \frac{21}{100}$
