Why Do We Multiply & Divide by the Same Number in Fractions? Adding & Subtracting Unlike Fractions

Have you ever wondered WHY we must multiply or divide the numerator and denominator by the same number when adding or subtracting unlike fractions? In this video, we move beyond just "following the rules" to understand the mathematical logic behind creating equivalent fractions. The concept of Equivalent Fractions: Why multiplying by the same number doesn't change the value. The "Identity Property": Understanding that multiplying by $n/n$ is just like multiplying by 1! Step-by-step examples of adding and subtracting unlike fractions using this logic. By the end of this lesson, you won't just know how to do it—you'll know why it works! What you will learn: ✅ Why we find a Common Denominator. ✅ The role of the "Same Number Rule" in keeping fractions balanced. ✅ How to apply this to solve any addition or subtraction problem with unlike fractions. Perfect for students in Grade 4, Grade 5, Year 4, Year 5, and anyone preparing for KS2 SATs or looking to strengthen their math foundations.
