Răspuns:
3,14 = [tex]\frac{314}{100}[/tex]
2,(8) = [tex]\frac{26}{9}[/tex]
5,2(3) = [tex]\frac{471}{90}[/tex]
Explicație pas cu pas:
[tex]3,14 = \frac{314}{100}[/tex]
[tex]2,(8) = 2\frac{8}{9} = \frac{9 * 2 + 8}{9} = \frac{26}{9} \\\\5,2(3) = 5 \frac{23 - 2}{90} = 5 \frac{21}{90} = \frac{90 * 5 + 21}{90} = \frac{471}{90}[/tex]
