Put the steps in correct order to prove that if x is irrational, then 1/x is irrational using contraposition.
a. Substitute 1/x = p/q, to obtain x = 1/(1/x) = 1/(p/q) = q/p.
b. Hence x is rational.
c. If 1/x is rational, then 1/x = p/q for some integers p and q with q ≠0. Observe that p is not 0 either, because 1/x is not 0.
d. Observe that x is the quotient of two integers with the denominator nonzero.
