Estimating Quotients of Decimals

The video tutorial focuses on estimating quotients of decimals using compatible numbers, similar to estimating products. It explains the concept of rounding numbers to make them compatible for easier calculation. The tutorial provides examples, such as rounding 83.9 to 180 and using compatible numbers like 3 and 18, to demonstrate the estimation process. It emphasizes the importance of choosing numbers that simplify calculations and offers practice exercises to reinforce the concept. The video concludes with a brief summary of the techniques discussed.
