Adding and Subtracting Fractions

This video tutorial covers the process of adding and subtracting fractions with different denominators. It explains how to find common denominators and adjust numerators accordingly. Through examples involving beads, the video demonstrates how to add and subtract fractions by finding the least common multiple. The tutorial emphasizes the importance of matching denominators before performing operations and concludes with a final example to reinforce the concepts.

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

• Find a common denominator.

• Multiply the fractions.

• Add the numerators directly.

• Subtract the smaller fraction from the larger one.

Why do numerators get 'jealous' when creating common denominators?

• They want to be divided by the same number.

• They want to be multiplied by the same number as the denominator.

• They want to be added to the denominator.

• They want to be subtracted from the denominator.

What happens to the numerator when the denominator is multiplied by a number?

• It remains the same.

• It is divided by the same number.

• It is multiplied by the same number.

• It is subtracted by the same number.
