Question
Alex wants to multiply a number by 12. First, she multiplies the number by 6. What number does she now need to multiply her answer by?
Solution 1
Alex needs to multiply her answer by 2. This is because she has already multiplied the number by 6, and 6 times 2 equals 12. So, to get the same result as multiplying the original number by 12, she now needs to multiply her current answer by 2.
Solution 2
Alex now needs to multiply her answer by 2. This is because 6 (her first multiplication factor) times 2 equals 12, which is the original number she wanted to multiply by.
