Fraction Subtraction - Problem Simplification - Basic - Two Changed Denominators (Level 1)

This math topic focuses on practicing fraction subtraction by simplifying problems where both fractions have different denominators. The exercises involve finding a common denominator and rewriting each fraction so that both have the same denominator before performing the subtraction. The task tests the student's ability to reconfigure and simplify basic fraction problems with two different denominators, enhancing their skills in fraction addition and subtraction at an advanced level. Each problem gives multiple options, asking the learner to identify the correctly set up expression.
