Calculating Percentages and Estimations

The video tutorial explains how to estimate using benchmark percents like 25%, 50%, 75%, 100%, and 10%. It demonstrates how to round numbers for easier calculations and provides examples using $58.99, rounded to $60, to find these percentages. The tutorial also covers how to estimate other percentages, such as 15%, by combining known benchmarks.
