Understanding Percentages and Fractions

In this video, Mr. Almeida explains how to solve percent problems by finding the whole. He begins with an introduction to percents, explaining that a percent is a rate per 100. He then demonstrates how to simplify percents using fractions. The video includes two word problems: one about milkshake sales and another about a hiking trip. Mr. Almeida uses ratio tables to find the whole in each problem, emphasizing the importance of understanding percents as parts of a whole.
