Virtually every number in one's daily life is a real number. The only exceptions occurwhen an individual is a mathematician, a Physicist, or an electrical engineer workingwith AC.So considering the population as a whole, it's nearly correct to say that the real numbershave all of the importance, and no non-real numbers are important at all.
Umm... first of all this question isn't grammatically correct, but I'll answer the question, "How useful are whole numbers in real life?". They are useful to know when you when you are taking an algebra class:)
-3 is a real, rational, whole integer. But then, -- All integers are real rational whole numbers. -- All whole numbers are real rational integers. -- All rational numbers are real. -- All counting numbers are real, rational, whole integers.
There are many situations where integers are simply not enough. However, "real numbers" are mainly of theoretical importance; for most practical situations, numbers that have a limited number of decimals work quite well.
Decimals are real numbers. Furthermore, integers and whole numbers are the same thing.

The population of your town, state, country will all be whole numbers but you would not use the raw numbers for any of them.

No, not all. All numbers are Real Numbers. * * * * * All numbers are not real numbers: there are complex numbers and others. Also, all real number are not whole numbers. sqrt(2) or pi, for example are real numbers but not whole numbers.

I think you can answer this question on your own. Find a number, anywhere (house number, price of a hot dog, phone number). These all use real numbers.
3. It is real, rational and whole. Rational numbers are numbers that can be written as a fraction.
The answer depends on the percentage. In many real-life cases they are proper fractions and therefore cannot be converted to whole numbers.
