Creating Equivalent Fractions Using the Identity Principle

The video tutorial explains how to create equivalent fractions using the identity principle of multiplication and division. It introduces models like pizza pies to represent common fractions and demonstrates how to determine if fractions are equivalent. The identity principle is used to multiply or divide fractions by a fraction name for one, creating equivalent fractions with more or fewer parts. Simplifying fractions involves dividing by the greatest common factor. A practical example with cookies illustrates these concepts. The lesson concludes with a recap of the methods for creating and simplifying equivalent fractions.

Which model can be used to visually represent equivalent fractions?

• A number line

• A scatter plot

• A bar graph

• A pizza pie

What does the identity principle state about multiplying or dividing a number by one?

• The result is always doubled

• The result is always the original number

• The result is always one

• The result is always zero

How can you create an equivalent fraction with more equal parts?

• By dividing by a fraction name for one

• By adding a fraction name for one

• By subtracting a fraction name for one

• By multiplying by a fraction name for one

What is the greatest common factor used for when reducing fractions?

• To add to the numerator and denominator

• To find the smallest number that divides both the numerator and denominator

• To find the largest number that divides both the numerator and denominator

• To multiply the numerator and denominator

If you ate 9 out of 27 cookies, what fraction of the cookies did you eat in simplest form?

• 1/4

• 1/3

• 1/5

• 1/2
