Ex1.3, 4 Express 0.99999β¦in the form π/π . Are you surprised by your answer? With your teacher and classmates discuss why the answer makes sense. Let x = 0.9999β¦.. Multiplying equation (1) with 10 10x = 10 Γ (0. 999β¦) 10x = 9. 999β¦ Subtracting (2) from (1) i.e. (2) β (1) 10x β x = 9.9999β¦ β 0.9999β¦ 9x = 9 x = 9/9 x = 1 Thus, 0.9999β¦ = 1
