Question

1,(2)÷0,(2)=???
Va rog ajutati-ma

Answer 1

1,(2)=(12-1)/9=11/9
0,(2)=2/9
Deci 1,(2)/0,(2) devine (11/9)/(2/9). Din regula impartirii fractiilor=>11/9x9/2=11/2=5,5

Answer 2

1,(2)=[tex] \frac{12-1}{9} = \frac{11}{9} [/tex]
0,(2)=$\frac{2}{9}$
deci:$\frac{11}{9} : \frac{2}{9} = \frac{11}{9} * \frac{9}{2} = \frac{11}{2}$
