Description: Sal compares two decimals using place value. Created by Sal Khan. We're asked to compare 156.378 to 156.348. So I assume that they're asking us which of these is greater. So let's first go to the hundreds place. And you could view this as, to some degree, the most significant place. The 1 in the hundreds place represents a lot more than a 1 in the tens place or a 1 in the six's place.*Teacher Advisor is 100% free.
