We use the denominator below the numerator.
we had to do math that is denominator
Either: when given a fraction with a surd as the denominator, rationalising the denominator; Or, when given a fraction with a complex denominator, to make the denominator real.
Not necessarily. The denominator need not have any real zeros, for example x2+1. Not necessarily. The denominator need not have any real zeros, for example x2+1. Not necessarily. The denominator need not have any real zeros, for example x2+1. Not necessarily. The denominator need not have any real zeros, for example x2+1.
When reducing fractions to their simplest form the greatest common factor of their numerator and denominator must be found.
Whenever we are dealing with rational fractions.

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.
Well, since there is no such thing as a sphare in the real world, it is a bit hard to tell what it can or cannot use.
Use the rules of division for complex numbers. Just divide 1 / (4 + 3i). This requires multiplying numerator and denominator of this fraction by (4 - 3i), to get a real number in the denominator.
All fractions (with whole numbers in the numerator and the denominator - zero in the denominator is not allowed) are rational numbers, and therefore also real numbers.
use a absolute value to represent a negative number in the real world
