Cześć ;-)
a)
[tex]\dfrac{\frac{3}{2}}{\frac{9}{4}}=\dfrac{3}{2}:\dfrac{9}{4}=\dfrac{3}{2}\cdot\dfrac{4}{9}=\dfrac{12}{18}=\boxed{\dfrac{2}{3}}[/tex]
b)
[tex]\dfrac{\frac{3}{11}}{\frac{5}{11}}=\dfrac{3}{11}:\dfrac{5}{11}=\dfrac{3}{11}\cdot\dfrac{11}{5}=\boxed{\frac{3}{5}}[/tex]
c)
[tex]\dfrac{\frac{5}{9}}{3}=\dfrac{5}{9}:3=\dfrac{5}{9}\cdot\dfrac{1}{3}=\boxed{\frac{5}{27}}[/tex]
d)
[tex]\dfrac{\frac{4}{7}}{\frac{7}{8}}=\dfrac{4}{7}:\dfrac{7}{8}=\dfrac{4}{7}\cdot\dfrac{8}{7}=\boxed{\frac{32}{49}}[/tex]
Pozdrawiam!
