Comparing Fractions: Key Concepts and Techniques

The video tutorial explains how to determine if two fractions, 30/45 and 54/81, are equivalent by simplifying them to their lowest terms. The process involves finding the greatest common factor for each fraction and dividing both the numerator and the denominator by this factor. Both fractions simplify to 2/3, confirming they are equivalent.

What is the first step in determining if two fractions are equivalent?

• Subtract the denominators

• Simplify both fractions to their lowest terms

• Multiply the numerators

• Add the fractions
