KS2 Primary Maths Age 9-13 - Fractions, Decimals and Percentages: Adding and Subtracting Fractions - Explained

The video tutorial explains how to add fractions with different denominators. It starts by converting mixed numbers into improper fractions, then finds the lowest common denominator. The fractions are adjusted to have the same denominator, allowing for straightforward addition. The result is simplified into a mixed number, providing a clear solution to the problem.

What is the first step when adding fractions with different denominators?

• Find the lowest common denominator

• Convert to improper fractions

• Add the numerators directly

• Multiply the fractions

How do you find the lowest common denominator for fractions with denominators 5 and 10?
