Dividing Fractions Using a Common Denominator

The video tutorial explains how to divide fractions using common denominators. It starts with a basic example of dividing 1/2 by 1/4 using a model. Then, it introduces the concept of using common denominators to simplify division problems, such as dividing 1/4 by 1/8. The tutorial provides a practical example involving applesauce to demonstrate the method. Finally, it discusses when the common denominator strategy is most effective, particularly when dividing a larger fraction by a smaller one.

How many groups of 1/4 are in 1/2?

• 3

• 2

• 1

What is the equivalent of 1/4 when using a common denominator with 1/8?

• 2/8

• 1/8

• 4/8

• 2

How many 3/4 cup servings can Sorcha make from 3 cups of applesauce?

• 5

• 4

• 3

• 2

What is the equivalent fraction of 3 when using a common denominator with 3/4?

• 11/4

• 10/4

• 12/4

• 9/4

When is the common denominator strategy most effective?

• When dividing two fractions with the same numerator

• When dividing a smaller fraction by a larger fraction

• When dividing a larger fraction by a smaller fraction

• When dividing two whole numbers

Why is the common denominator strategy not efficient for dividing 6/7 by 4?

• Because 6/7 is already a whole number

• Because 4 cannot be expressed as a fraction

• Because it results in a non-divisible numerator

• Because 6/7 is smaller than 4
