by definition, the rational ones are the ones that can be written in the form a%2Fb where and b are integers and b does not equal 0
15=15%2F1-rational number
219=219%2F1-rational number
sqrt%289%29=3=3%2F1-rational number
3995=3995%2F1000-rational number
so, { 15,219,sqrt%289%29,+3.995 }- the set of numbers contain rational numbers
