depends on what the problem is
Domain: All Possible "x" values Range: All possible "y" values
domain
From a mathematical point of view, it is not at all important. Any equivalent fraction is just as good, so simplification makes no difference whatsoever. However, the simplest form involves the smallest integer values for the fraction and most people find it easiest to understand and to work with small numbers. Also, examiners expect you to be able to simplify fractions.
The sum of a fraction? Well, to find the sum of the fraction all you do is divide both top and bottom numbers.
The "range".
It is called the domain.
What are all the possible whole number values for 7
Domain: All Possible "x" values Range: All possible "y" values
The range of a function is the set of all of the possible values that it can take on as an output value. You find the range by inspecting the function and seeing first what the domain is, and then what the range would be for that domain. The domain, then, is the set of all of the possible values that it can take on as an input value.
Any fraction of the form n/(4*n) is an equivalent fraction. There are infinitely many possible values of n so there are infinitely many possible fractions. The universe is too small to record infinitely many numbers, so the answers cannot be listed.
The Range is the set of all possible output values of a function or relation.
