Charity Jars (Part 2) (Use equivalent fractions to solve word problems involving addition of fractions with like and unl

The video tutorial explains how to solve a problem involving jars of coins by using equivalent fractions. It begins by setting up the problem, where Alex's sister has a charity jar with coins. The tutorial then explains how to convert fractions to have a common denominator, using the example of 1/5 and 3/15. Finally, it demonstrates how to add these fractions to find the total amount of coins, resulting in the fraction 14/15. The lesson focuses on using equivalent fractions to add fractions with unlike denominators.
