a)
[tex]5 \times \frac{2}{3} = \frac{10}{3} = 3 \frac{1}{3} [/tex]
b)
[tex]3 \times \frac{9}{20} = \frac{27}{20} = 1 \frac{7}{20} [/tex]
c)
[tex] \frac{3}{5} \times 8 = \frac{24}{5} = 4 \frac{4}{5} [/tex]
d)
[tex] \frac{7}{13} \times 5 = \frac{35}{13} = 2 \frac{9}{13} [/tex]
e)
[tex] \frac{7}{9} \times 7 = \frac{49}{9} = 5 \frac{4}{9} [/tex]
Myślę że pomogłem ;)
