Estimating Quotients with Compatible Numbers

The video tutorial explains how to estimate decimal quotients using compatible numbers. It begins with an introduction to the concept of compatible numbers and how they can be used to estimate quotients of whole numbers. The tutorial then extends this concept to decimal numbers, providing several examples to illustrate the process. Each example demonstrates how to choose compatible numbers greater and less than the dividend to estimate the quotient. The video concludes with a call to action for viewers to like and subscribe.
