The video tutorial explains two methods for solving proportions: using the Least Common Multiple (LCM) and cross multiplication. The LCM method involves finding the smallest multiple that both denominators divide into, then multiplying both sides of the equation by this number. Cross multiplication is often simpler, involving multiplying the cross products of the fractions. Both methods require simplification, combining like terms, and solving the resulting equation. The tutorial emphasizes understanding both methods to choose the most effective one for different problems.
