Question

Daca a=0,2 si b=0,(2) , atunci raportul dintre a si b este....

Answer 1

a=0,2=2/10
b=0,(2)=2/9

Raportul=$\frac{0,2}{0,(2)} = \frac{ \frac{2}{10} }{ \frac{2}{9} } =\ \textgreater \ \ \frac{2}{10} : \frac{2}{9} =\ \textgreater \ \frac{2}{10} \ X \ \frac{9}{2} = \frac{9}{10} =0,9$

Answer 2

a=0,2  si b=0,(2)=2/9=0,2222222

a/b=0,90000090000009
a/b≈9/10
