Is 5 and one half a rational number?
5 = 5/1 is a rational number
Is a half a rational number?
Yes 1/2 is a rational number
Is one half a rational or irrational number?
As a number which can be expressed as a fraction, 1/2 is a rational number.
Is one half a integer?
No, one half which is 1/2 is not a integer. Its a rational number.
Is one half a rational number or a natural number?
Rational: yes. Natural: no.
Is negative one half an irrational number?
No because -1/2 is a rational number expressed as a fraction
Is there a smallest positive rational number?
1/infinity? * * * * * Nice idea but unfortunately that is not a rational number, which is defined as the ration of two integers, x/y where y > 0. Since infinity is not an integer, the suggested ratio is not a rational number. The correct answer is that there is no such number. If any number laid claim to being the smallest positive rational, then half of that number would have a better claim. And then a half of THAT number would be a positive rational that was smaller still. And so on.
Can half of an irrational number be rational?
No, it cannot. The product of a rational and irrational is always irrational. And half a number is equivalent to multiplication by 0.5
Is a half an rational number?
yes
An integer that is not rational?
The are an infinite number of rational numbers that are not integers, because a rational number is a number that is written as a ratio of two integers. For examble, 1/2 (i.e. a half) is a non-integer rational number. This form is generally called a fraction.
All rational numbers are integers?
A rational number is a number which can be expressed as the quotient of two integers, a quotient being the solution to a division sum. Therefore, 1/2, or one half, is a rational number, equal to 0.5. However, 1/3, or one third, is an irrational number, because if you had to write the number out as a decimal, the number would continue to recur. Therefore, all integers are rational numbers, but not all rational numbers are integers. EDIT: 1/3 is a rational number, whoever said it wasn't is a moron.
Is one and a half a rational number?
Yes.
