<prompt> Theha bopaki ba lipalo bakeng sa polelo ena.Bakeng sa linomoro tsohle tse positi a le b, aba  <response>: Instruction in English: Construct a mathematical proof for this statement. . Response in English: Proof: Let a and b be two positive numbers. That is, a0 and b0.Adding b to both sides of the inequality a0, we get:ab b, since b0, we know that bb-1.Hence, ab b b-1.Since, a b-1, we can substitute b-1 with a in the above inequality.Therefore, aba.This completes the proof. . Response in Sesotho: Bopaki: E re a le b e be linomoro tse peli tse positive. Ke hore, a0 le b0. Ho kenyelletsa b mahlakoreng ka bobeli a ho se lekane a0, re fumana: ab b, ho tloha b0, rea tseba hore bb-1. Kahoo, ab b b-1. Kaha, a b-1, re ka kenya b-1 sebakeng sa a ho se lekane se ka holimo. Ka hona, aba. Sena se phethela bopaki.
