a)
[tex]5 \times \frac{7}{30} = 1 \times \frac{7}{6} = \frac{7}{6} = 1 \frac{1}{6} [/tex]
b)
[tex]8 \times 8 \frac{1}{4} = 8 \times \frac{33}{4} = 4 \times \frac{33}{1} = 132[/tex]
c)
[tex]4 \times \frac{8}{15} = \frac{32}{15} = 2 \frac{2}{15} [/tex]
d)
[tex]7 \times 2 \frac{3}{8} = 7 \times \frac{19}{8} = \frac{133}{8} = 16 \frac{5}{8} [/tex]
Myślę że pomogłem ;)
