Fraction Subtraction - Missing Value (Mixed) - Two Changed Denominators (Level 2)

This math topic involves practicing advanced fraction subtraction with mixed numbers and multiple changed denominators. Students focus on finding the missing value that makes given subtraction equations correct. Each problem presents a fraction subtraction equation where one part of the equation is missing, and students must select the correct answer from multiple choices. Each equation involves different denominators, requiring knowledge of fraction subtraction, finding common denominators, and reducing fractions to their simplest form. This skill set falls under a broader unit on Fraction Addition and Subtraction at an advanced level.
