Completați cu numerele care lipsesc, astfel încît propozițiile să fie adevărate:
$a) \frac{1}{2} = \frac{}{4} = \frac{3}{6} = \frac{4}{} = \frac{}{10}$
$b) \frac{1}{3} = \frac{}{4} = \frac{3}{9} = \frac{4}{} = \frac{}{15}$
$c) \frac{1}{4} = \frac{2}{} = \frac{3}{} = \frac{4}{ } = \frac{5}{}$
$d) \frac{1}{5} = \frac{2}{} = \frac{3}{} = \frac{4}{} = \frac{5}{}$
