Understanding Number Formats and Ordering

The video tutorial explains how to order a list of numbers expressed in different formats: percentages, decimals, fractions, and mixed numbers. It demonstrates converting each format into decimals for easy comparison. The tutorial covers converting percentages by dividing by 100, converting fractions through division, and converting mixed numbers by rewriting them as improper fractions. Finally, it orders the numbers from largest to smallest using their decimal equivalents, emphasizing estimation for quick comparisons.
