What is a ration number?
A rational number is a number that can be expressed as the quotient (i.e. ratio or fraction) of two integers. ( Integers are rational since any integer, n ,can be written as n/1 )Rational numbers are numbers that can be expressed as fractions whereas Irrational Numbers cannot be expressed as fractionsA rational number is a number that terminates or ends. As in a perfect square like: 144; 36; 625 etc.More specifically, a rational number is a number that can be expressed as the ratio of two integers, where the denominator is not zero. 1.37, for instance, is rational because it can be expressed as 137 / 100.It is any whole number even if it's a negative numberAny number that can be expressed as a fraction is a rational number whereas irrational numbers can't be expressed as a fractions.In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, p and q, with the denominator q not equal to zero. Since q may be equal to 1, every integer is a rational number.
Can a whole number be rational numbers?
Yes, rational numbers are numbers that can be expressed as the ratio of two integers. Whole numbers is a slightly ambiguous term but usually means either positive integers, or all integers (-3, -2, -1, 0, 1, 2, 3, ...) A whole number can be rational because 4 is a whole number and it can also be expressed as the ratio of two integers, in this case 4 and 1 example: 4 = 4/1 = 8/2 = 4
