Answer 1

If we answer that on here, then you won't learn it. The best thing you can do is to struggle through it, learn the process, so you will be better prepared come test time. I will tell you this, a rational number is a number that has a finite number of digits(for example 5 or 2/5=0.2) while an irrational number has an infinite number of digits(for example pi=3.14159...........).
