pi, or the square root of 2.
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.
1 + pi, 1 - pi. Their sum is 2.
That simply isn't true. The sum of two irrational numbers CAN BE rational, but it can also be irrational. As an example, the square root of 2 plus the square root of 2 is irrational.
Yes. 2*pi is irrational, pi is irrational, but their quotient is 2pi/pi = 2: not only rational, but integer.
No. pi/2 is a faction but it is not a rational number.
No. pi/2 is a fraction but, since pi is irrational, so it pi/2.
No, it is not.
No, it is not.
No. sqrt(2)/pi is not rational.
(pi) itself is an irrational number. The only multiples of it that can be rational are (pi) x (a rational number/pi) .
3.14 is a rational number pi is not. pi is not 3.14
If you multiply or divide an irrational number - such as pi - by ANY rational number (except zero), you will ALWAYS get an irrational 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.
pi, or the square root of 2.
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).
Pi is irrational.
