1.
a) [tex]-\frac{9}{4} * \frac{7}{3} = -\frac{21}{4} = -5\frac{1}{4}[/tex]
b) [tex](-7\frac{1}{5} ) : (-3\frac{1}{5} ) = (-\frac{36}{5} ) * (-\frac{5}{16} ) = \frac{9}{4} = 2\frac{1}{4}[/tex]
c) [tex](1,4) * (-5,07) = 7,98[/tex]
d) [tex]0,056 : -0,7 = -0,08[/tex]
2.
a) [tex]63 - 36 : 9 = 63 - 4 = 59\\[/tex]
b) [tex][17 - 4 - (-2)^3 ] * 9 = [17 - 4 - 8] * 9 = 5 * 9 = 45[/tex]
3.
a) 534, 382 = (te kreski falowane) 534,4
b) 801, 96548 = 801, 965
