Anyways, can it be written as irrational since the two integers of p and q are prime numberS?

irrational is when the numbers after the decimal point are just 'irrational' no pattern

I think you are trying find a tell all for irrational numbers, and i dont think there is.
it simply means that it cane be put in a RATIO of integers

it all changes after you complete basic calc, difEQ, and linear algebra.
things get very different once you get into calc analysis, real analysis, group theory/abstract algebra, differential geometry, ....these are all things you will do, and none of it will be anything like what you are doing now.

they are all realted....it would be like learning to throw a frisbie before you have learned to throw a ball. you dont need to learn how to throw the ball first, but it's probobally the best order to do it in.

I can't believe the answer to this question has become so huge (yeah a lot of it is irrelevant information).
An irrational number is one that cannot be put into the form of a fraction.
1/7 - although that is a repeating decimal .142857142857142857..., it is a rational number.

@wolf1728 you need to be careful with your wording
its not that it cant be written in the form of a fraction as \[\frac{\pi}{2}\]is a fraction and is irrational
the point is, that if the number is a real number and it cant be put in a ratio (fraction) where the numerator and denominator are integers then it is irrational.
