Comparing and Understanding Fractions

The video tutorial explains how to compare fractions using the Least Common Multiple (LCM). It begins by introducing the concept of LCM and its importance in comparing fractions with different denominators. The tutorial then demonstrates how to find the LCM of two denominators using skip counting or a multiplication chart. Once the LCM is identified, the fractions are adjusted to have a common denominator, allowing for easy comparison. The video concludes with a visual representation to reinforce the concept, showing that 7/10 is greater than 2/5.

What does LCM stand for?

• Lowest Common Measure

• Least Common Measure

• Lowest Common Multiple

• Least Common Multiple

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

• Add the fractions

• Find the LCM

• Multiply the fractions

Why do we need to find the LCM when comparing fractions?

• To simplify the fractions

• To find the greatest fraction

• To make the denominators the same

• To make the numerators the same

What does it mean if two fractions have the same denominator?

• They are equal

• They cannot be compared

• You can compare the numerators directly

• You need to find a new LCM
