Learn how to solve a proportion in three different ways z/3 = 10/6

The video tutorial covers three methods for solving equations involving fractions. The first method involves eliminating fractions by multiplying by the least common denominator. The second method uses inverse operations to solve equations by identifying and reversing operations on the variable. The third method, cross multiplication, is used for solving proportions by equating two ratios. Each method is explained with examples to ensure understanding.
