Multiplying Decimals Using Partial Products

This video tutorial explains how to multiply decimals using the partial products method. It begins with an introduction to the method, followed by setting up a diagram to separate whole numbers and decimal parts. The tutorial then demonstrates multiplying whole numbers and decimals, calculating partial products, and finally, adding these products to find the final answer. The video concludes with a verification step to ensure the accuracy of the result.
