Description: Sal compares 9.97 and 9.798 using place value. Created by Sal Khan. So to figure out which one of these is greater, I like to start with the largest place values and then keep moving to smaller and smaller ones until we actually see a difference. So right now, we could view this. Let's just write the whole numbers out. So far, out of the two digits, the two places we've looked at, this one on the right is 9 plus 7/10.
