Question

If the product of 485 x 35 is 16,975, what is the product of 485 x 3.5? How do you know?

Answer 1

Explanation:

Without doing any math, 1,697.5

35.0 and 16,975 is the original

3.5 is 35.0, but they moved the decimal one point to the left

We do the same for the answer

16,975... we move the comma one point to the left and get 1,697.5
