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.
Daily transactions, calculations are very easy to work out by all irrespective of literacy.
Yes, all natural numbers are real numbers. Natural numbers are a subset of real numbers, so not all real numbers are natural numbers.
All rational numbers are real numbers.
Complex numbers are a proper superset of real numbers. That is to say, real numbers are a proper subset of complex 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.

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.

No. Natural numbers are a proper subset of real numbers.
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.
without numbers how can we compute
Real Numbers cannot be the square root of a negative number. Real Numbers are not divided by zero. Basically, Real Numbers cannot be anything that is undefined.
