Question

Which of the following steps could be used as a shortcut method to multiply 12 by 50?

Answer 1

We must remember that 50 x 2 = 100. Multiplying numbers by 100 would be easier since all we have to do is add two zeros after. For example, 62 x100 = 6200. Since we multiplied a number by 2, we must divide it by 2 after getting the product. To make this more clearer, for 12 x 50, for example, we have 12 x 50 = (12 x 100)/2 = 1200/2 = 600 Thus, the answer is C.

Answer 2

The answer is C. Multiply 12 by 100, then divide that result by 2.
