bardzo długie wiem, ale to tylko jego połowa, sama mam dwa razy więcej...

1.
a) 2 2\frac{1}{4} - 3\frac{1}{2} - 1\frac{7}{8}

b) 4\frac{1}{6} - 2\frac{2}{3} - 3\frac{1}{2}

c) 1\frac{2}{5}- 3\frac{3}{4}-2\frac{3}{10}

d) 2\frac{5}{6}- (1\frac{1}{4}+ 4\frac{3}{8})

e) 2\frac{6}{7}*(-\frac{14}{15} - 3\frac{1}{3}) * (-1\frac{4}{5})

f) -5\frac{1}{3} * (-1\frac{1}{2}) + \frac{5}{8} : (-3\frac{3}{4})

2.

a) (2\frac{3}{4} - 3\frac{2}{3}) : 1\frac{1}{2}

b) -3\frac{1}{4}:(3\frac{5}{8}-2\frac{1}{6}):(-2\frac{1}{2})

c) \frac{2}{7} * (-1\frac{3}{4}) -2\frac{1}{3}:(-1\frac{1}{6})

d) 2\frac{1}{3}+(1\frac{3}{7}-3\frac{3}{5})*(-\frac{7}{19})
