Belоw аre the steps fоr а prоof by contrаdiction of the following theorem: Theorem: There is no smallest positive real number. Put the steps of the proof in the correct order so that each step follows from previous steps in the proof. (a) This contradicts the assumption that r is the smallest positive real number. (b) Assume there is a smallest positive real number called r. (c) Consider r/2, which is a positive real number since r is positive. (d) Moreover, r/2 < r, since both are positive. Proof: [Step1]; [Step2]; [Step3]; [Step4].
