a)
[tex] \frac{4}{7} \div \frac{3}{5} = \frac{4}{7} \times \frac{5}{3} = \frac{20}{21} [/tex]
b)
[tex] \frac{1}{7} \div \frac{2}{5} = \frac{1}{7} \times \frac{5}{2} = \frac{5}{14} [/tex]
c)
[tex] \frac{2}{9} \div \frac{1}{4} = \frac{2}{9} \times \frac{4}{1} = \frac{8}{9} [/tex]
d)
[tex]6 \div \frac{1}{2} = 6 \times 2 = 12[/tex]
e)
[tex]5 \div \frac{2}{3} = \frac{5}{1} \times \frac{3}{2} = \frac{15}{2} = 7 \frac{1}{2} [/tex]
f)
[tex]12 \div \frac{7}{4} = 12 \times \frac{4}{7} = \frac{48}{7} = 6 \frac{6}{7} [/tex]
Myślę że pomogłem ;)
