Finding the Whole with Unit Fractions

In this video, Mr. Math Log teaches problem-solving using unit fractions. The lesson includes two examples: calculating the total number of marbles Trevor has when 1/3 are blue, and determining the total number of kittens in a pet store when 1/8 are calico. The strategy involves drawing diagrams to visualize and solve the fraction problems.

What is the main strategy discussed in this lesson for solving fraction problems?

• Using subtraction

• Using addition

• Using multiplication

• Drawing a diagram
