b)
[tex] \frac{3}{5} \times \frac{15}{1} = \frac{3}{1} \times \frac{3}{1} = \frac{9}{1} = 9[/tex]
c)
[tex] \frac{36}{1} \times \frac{2}{3} = \frac{12}{1} \times \frac{2}{1} = \frac{24}{1} = 24[/tex]
d)
[tex] \frac{16}{1} \times \frac{1}{2} = \frac{8}{1} \times \frac{1}{1} = \frac{8}{1} = 8[/tex]
e)
[tex] \frac{3}{10} \times \frac{8}{1} = \frac{3}{5} \times \frac{4}{1} = \frac{12}{5} = 2 \frac{2}{5} [/tex]
f)
[tex] \frac{10}{1} \times \frac{11}{12} = \frac{5}{1} \times \frac{11}{6} = \frac{55}{6} = 9 \frac{1}{6} [/tex]
g)
[tex] \frac{4}{1} \times \frac{23}{10} = \frac{2}{1} \times \frac{23}{5} = \frac{46}{5} = 9 \frac{1}{5} [/tex]
h)
[tex] \frac{2}{1} \times \frac{25}{6} = \frac{1}{1} \times \frac{25}{3} = \frac{25}{3} = 8 \frac{1}{3} [/tex]
i)
[tex] \frac{8}{1} \times \frac{7}{4} = \frac{2}{1} \times \frac{7}{1} = \frac{14}{1} = 14[/tex]
j)
[tex] \frac{100}{1} \times \frac{127}{40} = \frac{5}{1} \times \frac{127}{2} = \frac{635}{2} = 317 \frac{1}{2} [/tex]
k)
[tex] \frac{49}{15} \times \frac{30}{1} = \frac{49}{1} \times \frac{2}{1} = \frac{98}{1} = 98[/tex]
l)
[tex] \frac{27}{25} \times \frac{125}{1} = \frac{27}{1} \times \frac{5}{1} = \frac{135}{1} = 135[/tex]
Myślę że pomogłem ;)
