Symbol of rational numbers

Integers All integers are rational numbers. This is because any integer can be written as that integer over 1 (also an integer). This includes all negative numbers. For example, …

In mathematics, the irrational numbers (from in- prefix assimilated to ir- (negative prefix, privative) + rational) are all the real numbers that are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers. When the ratio of lengths of two line segments is an irrational number, the line segments are ...A number that can be made as a fraction of two integers (an integer itself has no fractional part). In other words a/b is a rational number when a and b are numbers like -2 or 7 or 123. But be careful: b cannot be zero. Examples: • 1/2 is a rational number • 0.75 is a rational number (3/4) • 1 is a rational number (1/1) In mathematics, division by zero is division where the divisor (denominator) is zero. Such a division can be formally expressed as , where a is the dividend (numerator). In ordinary arithmetic, the expression has no meaning, as there is no number that, when multiplied by 0, gives a (assuming ); thus, division by zero is undefined (a type of ...A rational number has an indefinitely repeating sequence of finite length l, if the reduced fraction's denominator contains a prime factor that is not a factor of the base. If q is the maximal factor of the reduced denominator which is coprime to the base, l is the smallest exponent such that q divides b ℓ − 1 . In fact, this is not the function used to count rational numbers. Imagine listing all of those numbers excluding the ones in which the fraction can be simplified. A possible bijection could be that function that gives the position of the rational number in that list. Since the list contains each rational number, the function is surjective.
