Obrigado quem me ajudar

Answer 1

$a)3,555...=3+ \frac{5}{9}= \frac{27+5}{9}= \frac{32}{9}\\\\b)7,222...=7+ \frac{2}{9}= \frac{63+2}{9}= \frac{65}{9}\\\\c)31,1333= 31\frac{13-1}{90}=31+ \frac{12}{90}= \frac{2790+12}{90}= \frac{2802}{90}= \frac{1401}{45}\\\\d)0,361361...= \frac{361}{999}\\\\e)5,0072444...=5+ \frac{724-72}{90000}=5+ \frac{652}{90000}= \frac{450000+652}{90000}= \frac{450652}{90000}$
