a) 66,53
b) 61,64
c) 250,92
d) 3,8512: 0,04=96,28
e) [tex]5\frac{1}{8} - 1\frac{5}{9} = \frac{41}{8} -\frac{14}{9} = \frac{369 - 112 }{72} =\frac{257}{72}[/tex]
f) [tex]3\frac{2}{3} * 1\frac{1}{2} =\frac{11}{3} *\frac{3}{2} =\frac{11}{1} *\frac{1}{2} =\frac{11}{2} =5\frac{1}{2}[/tex]
g) [tex]7\frac{5}{8} : \frac{3}{4} =\frac{61}{8} :\frac{3}{4}=\frac{61}{8} *\frac{4}{3} =\frac{61}{2} *\frac{1}{3} =\frac{61}{6} =10\frac{1}{6}[/tex]
