Jeopardy.
In the real world you can use the order of rational numbers. This is used a lot in math.
Unless you are an electrical engineer or a math teacher, every number you will ever use in a real world situation will be a real number.
Infinite answers, but if you want real whole numbers, than you can use 3*89
That is how they get the numbers that they put onto food containers as part of the nutrition label. They either take the whole thing and burn it in a calorimeter or they add up all the ingredients and use the calorimeter numbers known for those ingredients.

There are 10 numbers in the whole world 1,2,3,4,5,6,7,8,9,0 you use those numbers over and over again to make larger numbers.
The population of your town, state, country will all be whole numbers but you would not use the raw numbers for any of them.
Real numbers are all numbers which do not contain "i", when "i" represents the square root of -1. All numbers which do contain "i" are "imaginary numbers" and are not real numbers. This means that all numbers you'd ordinarily use are real numbers - all the counting numbers (integers) and all decimals are real numbers. So in answer to your question, all the real numbers that are not whole numbers are all the decimal numbers - including irrational decimals such as pi.
