Finding Common Denominators in Fractions

This video tutorial from MooMooMath and Science explains how to subtract fractions with different denominators. It demonstrates the use of factor trees to find a common denominator and provides step-by-step instructions for subtracting fractions. Two example problems are solved, illustrating the process of rewriting fractions with a common denominator and performing the subtraction. The video concludes with a reminder to practice kindness.
