Description: Discover a pattern when dividing by powers of 10. Created by Sal Khan. In this video, I just want to show you a quick shortcut because we're dividing something by a power of ten. Every time I multiply by 10, the decimal would shift to the right by one spot. If I were to do 99.061 divided by 10, we're going to shift the decimal in the other direction.*Teacher Advisor is 100% free.
