Estimating Quotients with Compatible Numbers

The video tutorial explains how to estimate quotients without using long division. It introduces the concept of using compatible numbers and decimal benchmarks as strategies for estimation. Three examples are provided: estimating 36.57 divided by 6, 22.41% divided by 4, and 4189 divided by 2. Each example demonstrates the use of compatible numbers or decimal benchmarks to simplify the division process and arrive at an estimated quotient.

Why is it important to avoid using long division when estimating quotients?

• It is too time-consuming.

• It requires a calculator.

• It doesn't help in understanding estimation strategies.

• It is not allowed in exams.
