A mixed fraction is a rational number because you can rewrite it as one integer over another.
The set of numbers which 3 does not belong is the set of even numbers.
A set is just a way of describing numbers, and numbers can be described in more than one way. If set A is (for example) all positive prime numbers, and set B is all numbers between 0 and 10, then there are some numbers (2, 3, 5, and 7) that could belong to both sets.
Negative fractions are part of all of the following sets, and a few more:Complex numbersReal numbersRational numbers (assuming you are talking about a fraction with integer numerator and denominator)
10 belongs to the set "natural numbers", but it can also belong to whole numbers, and rational numbers
9 belongs in the sets: -Natural number set, positive whole numbers -Integer number set, whole numbers -Rational number set, numbers that are not never ending -Real number set, basic numbers without i and that can be expressed in say amounts of apples -Complex number set, the set that contains both real and unreal numbers
Any number that can be written as a fraction belongs to the set of rational numbers.
