Finding Percentages: Fraction vs. Decimal Strategies

The video tutorial introduces two strategies for calculating percentages: the fraction multiplication approach and the decimal conversion method. The fraction method is useful when the percentage can be easily reduced to a fraction with a denominator that is a factor of the number. The decimal method involves converting the percentage to a decimal and multiplying, which is effective for any percentage. The tutorial provides examples and emphasizes choosing the easiest method for each problem.
