Question

Why 51.2 divided 6.4 has the same value as 5.12 divided 0.64?

Answer 1

The reason why both have the same value is because you are only moving the decimal place. The difference between 51.2 and 5.12 is that you divided 10 from 51.2 to get 5.12. Same goes for 6.4 and 0.64.

51.2 / 6.4 = 8

5.12 / 0.64 = 8
