Explicație pas cu pas:
[tex]\frac{4}{12} = \frac{4:2}{12:2} = \frac{2 : 2}{6 : 2} = \frac{1}{3} \\\\\frac{18}{12} = \frac{18:2}{12:2} = \frac{9}{6} \\\\[/tex][tex]\frac{36}{24} = \frac{36:2}{24:2} = \frac{18:2}{12:2} = \frac{9}{6} \\\\\frac{20}{30} = \frac{20:2}{30:2} = \frac{10}{15} \\\\\frac{28}{42} = \frac{28:2}{42:2} = \frac{14}{21} \\\\\frac{30}{45} nu merge simplificata prin 2, deoarece 45 nu se imparte la 2\\\\\frac{44}{66} = \frac{44:2}66:2} = \frac{22}{33}[/tex]
