Fraction Addition - Missing Value (Mixed) - One Changed Denominator (Level 3)

This math topic focuses on advanced fraction addition and subtraction with an emphasis on finding missing values in equations involving mixed numbers. The main skill practiced is the ability to determine which fraction, when added to another given fraction, results in a specific sum. Each problem presents a different fraction equation missing one value, which students need to calculate by selecting the correct option from multiple choices. The equations involve varying denominators, testing the student's proficiency in working with different fractional values and their addition.
