[tex]\frac{12}{28} =\frac{6}{14} =\frac{3}{7} =\frac{24}{56} \\ \\ \frac{125}{15} =\frac{250}{30}=\frac{25}{3} =\frac{75}{9} \\ \\ \frac{2^{3} }{8} = \frac{8}{8}= \frac{24}{24} =\frac{48}{48} \\ \\ \frac{1}{3} =\frac{4}{12} =\frac{6}{18} =\frac{8}{24}[/tex]
fractii egale inseamna ca daca avem [tex]\frac{a}{b} =\frac{c}{d}[/tex] ⇒ axd=bxc
