Solving Fraction Word Problems with Backward Strategies

The video tutorial teaches students how to solve word problems involving addition and subtraction of fractions by working backwards. It uses a hiking scenario where Emma needs to calculate the remaining distance to complete a trail. The tutorial demonstrates two methods: subtracting each segment from the total distance and adding segments together before subtracting from the total. It emphasizes understanding the problem, using common denominators, and choosing the most efficient method based on the problem's complexity.

What is the first step in solving a word problem involving fractions?
