Using Scale Factors to Find the Area of Scale Drawings

This video tutorial teaches how to identify equivalent fractions using a number line. It explains the roles of numerators and denominators in fractions and demonstrates how different fractions can represent the same point on a number line. Through various examples, including real-world scenarios, the video illustrates how fractions like 1/2 and 2/4 or 3/6 and 1/2 are equivalent, despite having different numerators and denominators.

What does the denominator in a fraction tell us when using a number line?

• The total length of the number line

• The color of the number line

• How many equal parts the whole is divided into

• The starting point on the number line

If two fractions have different numerators and denominators, can they still be equivalent?

• No, they must have the same denominators

• Yes, if they represent the same point on a number line

• No, they must have the same numerators and denominators

• Yes, if they have the same numerators

Which of the following pairs of fractions are equivalent?

• 3/6 and 1/3

• 2/5 and 3/5

• 1/3 and 1/4

• 1/2 and 2/4

What is the equivalent fraction of 4/10 when the number line is divided into fifths?

• 2/5

• 1/5

• 4/5

• 3/5

In the example of Nick and Ed, what fraction of a mile did Ed walk?

• 1/2

• 3/6

• 4/10

• 2/5

How can you determine if two fractions are equivalent using a number line?

• By adding them together

• By comparing their numerators

• By comparing their denominators

• By checking if they represent the same point on the number line

What is the main concept taught in this lesson?

• Adding fractions with different denominators

• Identifying equivalent fractions using a number line

• Subtracting fractions with the same numerators

• Multiplying fractions by whole numbers
