No, it is not.
If you multiply or divide an irrational number - such as pi - by ANY rational number (except zero), you will ALWAYS get an irrational number.
No, it is not.
No. sqrt(2)/pi is not rational.
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.
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).

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.
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.

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.
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).
No, since Pi is an irrational number, 2(pi) would still be irrational.

pi, or the square root of 2.
