Explicație pas cu pas:
1,2= [tex]\frac{12}{10}=\frac{6}{5}[/tex] ( am simplificat prin 2)
1,(3) = [tex]1\frac{3}{9}=1\frac{1}{3}=\frac{4}{3}[/tex]( am simplificat prin 3 apoi am introdus intregii in fractie)
0,14=[tex]\frac{14}{100}=\frac{7}{50}[/tex] ( simplificat prin 2)
[[tex][\frac{6}{5}+\frac{4}{3} *\frac{3}{20}]:\frac{7}{50}*2 = [\frac{6}{5} +\frac{1}{5}]*\frac{50}{7}*2=\frac{7}{5} *\frac{50}{7}*2=10*2=20[/tex]
