All integers are rational numbers. The easiest way to see that is to write an integer as a fraction with 1 as a denominator; 4=4/1=8/2; 5=5/1.
Any number that can be written as a ratio of two integers numbers is by definition a rational number ( it is a ratio---rational).
Any decimal number with a periodic decimal part can be cast as a fraction, so it is rational.
An irrational number is a number that cannot be written as a fraction.
Examples: PI, sqRT(2), Sqrt(3), SQRT(5), e. There is an infinite number of them.

The opposite of any number (be it integer, rational, or real) is the same number preceded by the negative sign.
Example : the opposite of a is -a (read it a negative a)
opposite of (-b) is -(-b)=b
A rational number is a number that can be written as a fraction. You should note that the set of rational numbers contains the set of all integers .
The opposite of 15/37 is -(15/37) which is equivalent to (-15)/37 and 15/(-37).

### What is the definition of rational numbers

Any number which can be written as the ratio of 2 integers, eg 22.5 , which can be written as 45/2. Every finite decimal is a rational number. Since in the general ratio p/q, q may equal 1, every integer is a rational number.

Many numbers do not fit this definition, the best known of which is Pi, or maybe SQRT(2).

### How do you represent the set of rational numbers in symbol form

A rational number is a number that can be expressed as a fraction with an integer numerator and a non-zero natural number denominator. Fractions are written as two numbers, the numerator and the denominator, with a dividing bar between them. In the fraction written mn or m represents equal parts, where n equal parts of that size make up one whole. Two different fractions may correspond to the same rational number; for example 1⁄2 and 2⁄4 are equal, that is: If the absolute value of m is greater than n, then the absolute value of the fraction is greater than 1. Fractions can be greater than, less than, or equal to 1 and can also be positive, negative, or zero. The set of all rational numbers includes the integers, since every integer can be written as a fraction with denominator 1. For example −7 can be written −7⁄1. The symbol for the rational numbers is Q (for quotient), also written .
