8.08 Compare fractions

Lesson

Are you ready?

Being able to identify how many equal parts are in a fraction model will help us compare fractions in this lesson. Let's try this problem to review. 

Here is a shape divided into parts, use it to answer the following questions.

  1. This shape has $\editable{}$ equal parts.

  2. If one part was shaded, that shaded part would be $\frac{\editable{}}{\editable{}}$ of the whole.

question 1

Which fraction is larger?

  1. $\frac{2}{4}$24
    A

    $\frac{3}{4}$34
    B

question 2

Which fraction is smaller?

  1. $\frac{3}{6}$36
    A

    $\frac{4}{6}$46
    B

 

Remember!

When comparing fractions, if the denominators are the same, then we can compare the numerators.

The denominator also tells us how many parts make up one whole.
