a)
[tex]\frac{ 3}{5} \times \frac{2}{7} = \frac{6}{35} [/tex]
b)
[tex] \frac{4}{5} \times \frac{3}{8} = \frac{1}{5} \times \frac{3}{2} = \frac{3}{10} [/tex]
c)
[tex] \frac{3}{4} \times \frac{8}{9} = \frac{1}{1} \times \frac{2}{3} = \frac{2}{3} [/tex]
d)
[tex] \frac{7}{15} \times \frac{10}{21} = \frac{1}{3} \times \frac{2}{3} = \frac{2}{9} [/tex]
e)
[tex]2 \frac{3}{4} \times \frac{1}{2} = \frac{11}{4} \times \frac{1}{2} = \frac{11}{8} = 1 \frac{3}{8}[/tex]
f)
[tex] \frac{5}{9} \times 4 \frac{1}{10} = \frac{5}{9} \times \frac{41}{10} = \frac{1}{9} \times \frac{41}{2} = \frac{41}{18} = 2 \frac{5}{18} [/tex]
g)
[tex]2 \frac{1}{2} \times 5 \frac{1}{3} = \frac{5}{2} \times \frac{16}{3} = \frac{5}{1} \times \frac{8}{3} = \frac{40}{3} = 13 \frac{1}{3} [/tex]
h)
[tex]3 \frac{3}{4} \times 4\frac{1}{5} = \frac{15}{4} \times \frac{21}{5} = \frac{3}{4} \times \frac{21}{1} = \frac{63}{4} = 15 \frac{3}{4} [/tex]
i)
[tex]5 \frac{6}{7} \times 4 \frac{2}{3} = \frac{41}{7} \times \frac{14}{3} = \frac{41}{1} \times \frac{2}{3} = \frac{82}{3} = 27 \frac{1}{3} [/tex]
Myślę że pomogłem ;)
