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.
Is 2 times pi 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 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.
Why is phi not the same as 22 over 7?
Firstly, it is pi, not phi. Second, 22/7 is a ratio of 2 integers. It is, therefore a rational number. pi is not a rational number, so it cannot be 22/7. It is a near enough approximation, though.
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.
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 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.
Is 2 times pi a rational number?
No, it is not.
Is 3.14 over 2 a rational number?
Yes, 3.14/2 is a rational number. 3.14/2 = 1.57 1.57 = 1 57/100 = 157/100. Do not confuse this with pi, which is 3.14159..., which is an irrational number.
Is an irrational number divided by an irrational number always a rational?
No. sqrt(2)/pi is not rational.
What numbers would you add to pie over 3 in order to obtain an answer that is a rational number?
You might add (-pi/3), in which case you obtain zero. Or you can choose any other rational number, and subtract that number minus pi/3. For example, if you want the result to be 2, , the number you must add is (2 - pi/3).
Is 2 pi a rational number?
No, since Pi is an irrational number, 2(pi) would still be irrational.
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.
What is an Example of a real number that is not a rational number?
pi, or the square root of 2.
Why is phi not the same as 22 over 7?
Firstly, it is pi, not phi. Second, 22/7 is a ratio of 2 integers. It is, therefore a rational number. pi is not a rational number, so it cannot be 22/7. It is a near enough approximation, though.
