Answer 1

c) $\frac{3}{5} . \frac{3}{4} = \frac{9}{20} = 0,25$

d) $\frac{16}{25} : \frac{18}{5} = \frac{16}{25} . \frac{5}{18} = \frac{8}{5} . \frac{1}{9} = \frac{8}{45} = 0,17$

e) $\frac{10}{14} : \frac{9}{49} = \frac{5}{7} . \frac{49}{9} = 5 . \frac{7}{9} = \frac{35}{9}$

f) $\frac{7}{3} : \frac{4}{18} = \frac{21}{2}$
