Which subset of the rational numbers best describes the dimensions of a rectangle
To which set of numbers does the number -12 belong?
It belongs to any set that contains it: for example, {4.75, -12, pi, sqrt(5), 29}. It belongs to the set of integers which is a proper subset of rational numbers which is a proper subset of real numbers which is a proper subset of complex numbers. So -12 belongs to all the above sets.
What is an example of an rational number?
A rational number is the set of number expressed in the form of a fraction a/b, where a and b are integers and b isn't equal to 0
