KS2 Primary Maths Age 13-17 - Fractions, Decimals and Percentages: Adding and Subtracting Fractions - Explained

The video tutorial explains how to subtract fractions by finding a common denominator. It begins with identifying the lowest common denominator (LCD) by listing multiples of the denominators. The fractions are then converted to equivalent fractions with the same denominator. The numerators are subtracted to find the final answer, which is clearly presented. The tutorial emphasizes the importance of showing work and concludes with the final answer, 5/24.

What is the first step in subtracting fractions with different denominators?

• Multiply the fractions.

• Add the numerators directly.
