Odpowiedź:
a)
[tex] - \frac{3}{4} - 8 \frac{5}{8} - 6 \frac{5}{6} - 1 \frac{3}{8} = - \frac{3}{4} - \frac{69}{8} - \frac{41}{6} - \frac{11}{8} = - \frac{211}{12} [/tex]
b)
[tex] - 14 \frac{1}{2} + ( - 7 \frac{3}{5} ) + 8 \frac{1}{5} + ( - 6.3) = - \frac{29}{2} - 7 \frac{3}{5} + \frac{41}{5} - 6.3 = - \frac{29}{2} - \frac{38}{5} + \frac{41}{5} - \frac{63}{10} = - \frac{101}{5} [/tex]
c)
[tex]20 + ( - 16.3) + 4 \frac{1}{3} + ( - 18 \frac{2}{3} = 20 - 16.3 + \frac{13}{3} - 18 \frac{2}{3} = 20 - \frac{163}{10} + \frac{13}{3} - \frac{56}{3} = - \frac{319}{30} [/tex]
d)
[tex] - 0.6 + 2 \frac{3}{8} + ( - 7 \frac{5}{8} ) + ( - \frac{1}{2} ) + 0 = - 0.6 + 2 \frac{3}{8} - 7 \frac{5}{8} - \frac{1}{2} = - \frac{3}{5} + \frac{19}{8} - \frac{61}{8} - \frac{1}{2} = - \frac{127}{20} [/tex]
Powinno być dobrze
