a)
[tex] \frac{4}{5} \times \frac{50}{1} = \frac{4}{1} \times \frac{10}{1} = 40[/tex]
b)
[tex] \frac{3}{4} \times \frac{32}{1} = \frac{3}{1} \times \frac{8}{1} = 24[/tex]
c)
[tex] \frac{4}{7} \times \frac{28}{1} = \frac{4}{1} \times \frac{4}{1} = 16[/tex]
d)
[tex]1 \frac{1}{3} \times \frac{27}{1} = \frac{4}{3} \times \frac{27}{1} = \frac{4}{1} \times \frac{9}{1} = 36[/tex]
Myślę że pomogłem ;)
