Odpowiedź:
a)
[tex] \frac{10}{1} \times \frac{3}{2} \times \frac{3}{2} = \frac{90}{4} = 22.5[/tex]
b)
[tex] \frac{12}{1} \times \frac{11}{4} \times \frac{4}{11} = 12[/tex]
c)
[tex] \frac{9}{2} \times \frac{2}{3} - \frac{7}{4} = \frac{3}{1} - \frac{7}{4} = \frac{12}{4} - \frac{7}{4} = \frac{5}{4} = 1.25[/tex]
d)
[tex] \frac{20}{1} - \frac{27}{4} \times \frac{4}{9} = \frac{20}{1} - \frac{3}{1} = 17[/tex]
