  • S1.B2.K3b, Tutorial 1, Question 3. Explanation for option C has been revised from “Multiplying the numerator and denominator by the same number (in this case, 1/3) is the same as multiplying by 1, the multiplicative identity, and 6/3 x 1 = 6/3, which simplifies to 2” to “Multiplying the numerator and denominator by the same number (in this case, 1/3) is the same as multiplying by 1, the multiplicative identity. 6 x 1/3 = 2, 3 x 1/3 = 1, and 2/1 = 2. Alternatively 6/3 x (1/3 ÷ 1/3 ) = 6/3 x 1 = 6/3, which simplifies to 2.”
