1,2in fractie -1intreg si 2 pe 10 bagam intregii in fractie-12/10
1,(3)in fractie-1intreg si 3pe 9 - bagam intregii in fractie -12/9
12/9×3/20= 36/180facem simplificarea prin 6 obtinem 6/30
12/10+6/30-amplificam prima fractie cu 3 a doua cu 1
36/30+6/30=42/30

42/30÷14/10
42/30×10/14putem simlifica in cruce
3/3×1/1
1×1=1
1×2=2
