# Positive Rational Numbers Symbol

**In other words, a rational number is positive, if its numerator and denominator are of the same sign.**

**Positive rational numbers symbol**.
1.2 representing the radical symbol as a positive and negative number;
A real number is a rational or irrational number, and is a number which can be expressed using decimal expansion.usually when people say number, they usually mean real number.
The ancient greek mathematician pythagoras believed that all numbers were rational, but one of his students hippasus proved (using geometry, it is thought) that you could not write the square root of 2 as a fraction, and so it was irrational.

The number 0 is both real and imaginary. Rational word is derived from the word ‘ratio’, which actually means a comparison of two or more values or integer numbers and is known as a fraction. The set of positive rational numbers :

• compare and order positive rational numbers. Positive rational numbers negative rational numbers; Perhaps one reason for this is because of the closure properties of the rational numbers.

Therefore, they consist of whole (0, 1 ,3 ,9, 26), rational (6/9, 78.98) and irrational numbers (square root of 3, pi). Rational numbers (fractions) the letter (q) is the symbol that is used to represent rational numbers. Any rational number can be called as the positive rational number if both the numerator and denominator have like signs.

\(\mathbb{q}\)\(_{+}\) = {x ∈ \(\mathbb{q}\) | x. For irrational numbers using \mathbb{i}, for rational numbers using \mathbb{q}, for real numbers using \mathbb{r} and for complex numbers using \mathbb{c}. Vocabulary math vocabulary there is no new vocabulary.

Fractions are numbers that are expressed as ratios. All are greater than 0: Points that fall in the right side of origin are considered as positive numbers, whereas numbers lying in the left side of origin are considered to be negative.
