Answer 1

Resposta:

 3,\overline{7}=3+0,\overline{7}=3+ \frac{7}{9}= \frac{34}{9}3,7=3+0,7=3+97=934

b) 2,\overline{51}=2+0,\overline{51}=2+ \frac{51}{99}=2+ \frac{17}{33}= \frac{83}{33}2,51=2+0,51=2+9951=2+3317=3383

c) 1,\overline{48}=1+0,\overline{48}=1+ \frac{48}{99}=1+ \frac{16}{33}= \frac{49}{33}1,48=1+0,48=1+9948=1+3316=3349

d) 5,\overline{324}=5+0,\overline{324}=5+ \frac{324}{999}=5+ \frac{12}{37}= \frac{197}{37}5,324=5+0,324=5+999324
