Quick Answer. Q represents rational numbers because all rational numbers are a quotient. This means that each rational number can be expressed by a fraction with a denominator other than zero and a numerator that is a whole number. Whole numbers, fractions and decimals are all rational numbers.
Then our sets included integers. The universal set for that is all the integers. In fact, when doing Number Theory, this is almost always what the universal set is, as Number Theory is simply the study of integers. But in Calculus (also known as real analysis), the universal set is almost always the real numbers. And in complex analysis, you guessed it, the universal set is the complex numbers.
