[1,2+1,(3)×3/20]:0,14×2​

Answer 1

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

0,14in fractie-14/10

42/30÷14/10

42/30×10/14putem simlifica in cruce

3/3×1/1

1×1=1

1×2=2
