Bài 1 :a,

\(17\frac{61}{100}=17+\frac{61}{100}=17+0,61=17,61\)

\(31\frac{501}{1000}=31+\frac{501}{1000}=31+0,501=31,501\)

\(30\frac{32}{100}=30+\frac{32}{100}=30+0,32=30,32\)

\(24\frac{7}{10}=24+\frac{7}{10}=24+0,7=24,7\)

\(18\frac{27}{10000}=18+0,0027=18,0027\)

b, \(5\frac{3}{10}=5+\frac{3}{10}=5+0,3=5,3\)

\(51\frac{62}{100}=51+\frac{62}{100}=51+0,62=51,62\)

\(90\frac{8}{100}=90+\frac{8}{100}=90+0,08=90,08\)

\(35\frac{3}{1000}=35+\frac{3}{1000}=35+0,003=35,003\)
