Solving a proportion by cross multiplication and inverse operations

The video tutorial explains how to solve proportions using two methods: inverse operations and cross-multiplication. The instructor first demonstrates the inverse operations method, emphasizing the importance of undoing operations to isolate the variable. Then, the cross-multiplication method is introduced as an alternative approach, highlighting its popularity and effectiveness. Both methods are shown to yield the same result, reinforcing the concept of solving proportions.
