Is 2 times 3.14 a rational Number?
Yes. 2 x 3.14 = 6.28 = 6 7/25 = 157/25 which is rational. If you are using 3.14 as an approximation to {pi}, then 2 x {pi} is not rational.
Is pi over 2 a rational number?
No, it is not.
Is an irrational number divided by an irrational number always a rational?
No. sqrt(2)/pi is not rational.
Is pi over 2 a whole integer rational or irrational number?
If you multiply or divide an irrational number - such as pi - by ANY rational number (except zero), you will ALWAYS get an irrational number.
What are some examples of a fraction but not a rational number?
A rational number is a fraction with an integer in the numerator, and a non-zero integer in the denominator. If you consider pi/2, pi/3, pi/4 (common 'fractions' of pi used in trigonometry) to be 'fractions', then these are not rational numbers.
Is 2 pi a rational number?
No, since Pi is an irrational number, 2(pi) would still be irrational.
Is 2 times 3.14 a rational Number?
Yes. 2 x 3.14 = 6.28 = 6 7/25 = 157/25 which is rational. If you are using 3.14 as an approximation to {pi}, then 2 x {pi} is not rational.
Is every fraction on a rational number?
No. pi/2 is a faction but it is not a rational number.
Are all fractions rational numbers?
No. pi/2 is a fraction but, since pi is irrational, so it pi/2.
Is pi over 2 a rational number?
No, it is not.
Is an irrational number divided by an irrational number always a rational?
No. sqrt(2)/pi is not rational.

What is an Example of a real number that is not a rational number?
pi, or the square root of 2.
Are there real number that are not rational number?
A real number dosen't have to be a rational number as a real number can be rational or irrational i.e the root of 2 is irrational and real. So is (pi).
Find two irrational numbers whose sum is a rational number?
(pi - 1) and (2 - pi) Sum = (pi - 1 + 2 - pi) = 1
Is 2 over 7 rational?
A rational number, by definition, is a number that can be written as a fraction. So, yes, 7/2 is a rational number An example of an irrational number would be pi, which cannot be expressed as a fraction.
