Are all integers 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).

A rational number is a number that can be expressed as the ratio of two integers. See http://en.wikipedia.org/wiki/Rational_number

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).

A rational number is any number that can be expressed as a fraction of 2 integers, this includes top heavy fractions.

Yes, all integers are rational numbers. Adding, subtracting, multiplying and dividing any 2 integers results in a rational number.

A rational number is a number that can be expressed as the RATIO (see rational) of two integer (whole) numbers. 8 is an integer, and so is 3. The number 8/3 is a RATIO of two integers :it fits the definition of a rational number.

A rational number is any number that can be expressed as a fraction, that is, as a ratio of two integers. See http://en.wikipedia.org/wiki/Rational_number

rational number. Any number that can be written as the ratio of two integer numbers is a rational.

hi maybe the formula below will help you

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 m⁄n 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 .
