a number that can be expressed as a ratio of two integers a/b with b not equal to zero; for example 3/4, 7, .5, .75, .333..., 7.5 Pi; the square root of 2, the square root of 3, .01001000100001..., etc. are not rational numbers
see fraction any number that can be written in the form a/b where a and b are integers and b cannot equal 0. It is a negative rational number if it is less than zero i.e. either a or b, but not both, is negative.
A rational number is a number that can be expressed as the ratio of two integers without the decimal representation of the number going on forever with a repeating pattern. If the decimal representation continues forever with a repeating pattern, a number is an irrational number.
Any number that can be represented in the form a/b, where and are integers and is not 0. Also, any number that can be represented by a terminating decimal or repeating decimal. 2/3, -2/3, 0.5, -0.5, and 0.333 … are rational numbers.
A rational number is a number that can be expressed in the form a/b, where a and b are integers and bâ‰ 0. For example, 0, 1/2, and -41 are rational numbers. Each rational number corresponds to a unique point on the number line (but most points on the number line do not correspond to a rational number -- they correspond to an irrational number).
A number that can be expressed as the ratio, or quotient, of two integers, a/b, provided b Í°0. Rational numbers can be expressed as common fractions or decimals, such as 3/5 or 0.6. Finite decimals, repeating decimals, mixed numbers and whole numbers are all rational numbers. Nonrepeating decimals cannot be expressed in this way, and are said to be irrational.
In mathematics, a rational number is a number which can be expressed as a ratio of two integers. Non-integer rational numbers (commonly called fractions) are usually written as the vulgar fraction \tfrac ab, where b is not zero.
