This hard-level worksheet contains 23 problems designed for 4th Grade students practicing equivalent fractions. Hard worksheets feature challenging problems including multi-step questions, missing values, and real-world applications to push students further.

Equivalent fractions are one of the most important and most tested fraction concepts. Understanding that a fraction can be expressed in infinitely many equivalent forms is the foundation for simplifying fractions and finding common denominators.

  • Identify equivalent fractions using visual models
  • Generate equivalent fractions by multiplying numerator and denominator by the same number
  • Recognize that 1/2, 2/4, and 3/6 all represent the same amount
  • Simplify fractions to lowest terms by dividing by common factors
  • Use equivalent fractions to find common denominators for comparison

How to Solve: Worked Example

Example Problem: Simplify 18/24 to its lowest terms.
Solution Steps:
  1. Find the greatest common factor (GCF) of 18 and 24.
  2. Factors of 18: 1, 2, 3, 6, 9, 18.
  3. Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.
  4. The GCF is 6.
  5. Divide both numerator and denominator by 6: 18 ÷ 6 = 3, 24 ÷ 6 = 4.
  6. 18/24 = 3/4.
Answer: 3/4
