Prove R is rational and S is irrational then R plus S must be irrational?
Let R + S = T, and suppose that T is a rational number.The set of rational number is a group.This implies that since R is rational, -R is rational [invertibility].Then, since T and -R are rational, T - R must be rational [closure].But T - R = S which implies that S is rational.That contradicts the fact that y is an irrational number. The contradiction implies that the assumption [that T is rational] is incorrect.Thus, the sum of a rational number R and an irrational number S cannot be rational.
Is -1.66 a rational or irrational number?
If the 6's continue, it is -5/3, and therefore it is rational. If they do not continue, it is -166/100, and still rational.

How do you find equivalent rational number s?
Given a rational number, express it in the form of a ratio. You can then calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any non-zero integer.
