Adding Decimals and Inequalities

The video tutorial covers a series of math problems involving decimals, fractions, and comparisons. It begins with a swim meet problem where times are added and converted to decimals. The tutorial then moves to locating times on a number line and converting them to fractions. Next, it compares distances using inequality symbols. The video also includes a cost calculation problem using decimals and fractions, and concludes with an explanation of how container sizes affect volume measurements.
