Converting Percentages to Fractions

This video tutorial by Professor Reginaldo Moraes on Professor Marcos' channel teaches how to convert percentages into fractions. It covers the basic concept of dividing by 100 and provides multiple examples, including 12%, 27%, 60%, 12.5%, 50%, and 40%. Each example is broken down into steps, showing how to simplify fractions to their irreducible form. The video emphasizes understanding divisibility rules to aid in simplification and encourages viewers to practice for better comprehension.
