Lesson 13 – Subtracting Fractions with the Same Denominator

Objective:

At the end of this lesson, students should be able to subtract fractions with the same denominator.



We can subtract fractions with the same denominator. We maintain one of the denominators and subtract the numerator as we did with the addition of fractions with the same denominator. In other words, we find the least common multiple (LCM).
