a)
[tex] \frac{5}{6} \times 45 = \frac{5}{6} \times \frac{45}{1} = \frac{225}{6} = 37.5[/tex]
[tex]0.6 \times 50 = \frac{6}{10} \times \frac{50}{1} = \frac{6}{1} \times \frac{5}{1} = 30[/tex]
[tex]37.5 > 30[/tex]
Zatem prawda
b)
[tex]2 \frac{1}{3} \times \frac{4}{7} = \frac{7}{3} \times \frac{4}{7} = \frac{1}{3} \times \frac{4}{1} = \frac{4}{3} = 1 \frac{1}{3} [/tex]
Prawda
