`3,5 = 35/10 = 30/10 + 5/10 = 3 + 5/10 = 3 5/10`
`6,33 = 633/100 = 600/100 + 33/100 = 6+33/100=6 33/100`
`18,05 = 1805/100 = 1800/100 + 5/100 = 18+5/100=18 5/100`
`217,908 = 217908/1000 = 217000/1000 + 908/1000 = 217 + 908/1000 = 217 908/1000`
3,5 \(=3\dfrac{5}{10}\)
6,33 \(=6\dfrac{33}{100}\)
18,05 \(=18\dfrac{5}{100}\)
217,908 \(=217\dfrac{908}{1000}\)
