Adding and Simplifying Fractions

In this video tutorial, Mrs. Cox teaches how to add unlike fractions using different methods, including the Math Antics way and her preferred stacking method. The lesson covers several examples, such as adding 5/8 and 3/10, 3/5 and 1/4, and 4/7 and 1/8, with a focus on finding common denominators and simplifying results. Real-life applications, like calculating the fraction of pizza eaten and newspaper delivery, are explored. The video also includes a test practice problem to find equivalent expressions for a sum of fractions.
