5.06 Compare fractions

Lesson

Being able to plot a fraction on a number line can help us compare fractions in this lesson. Let's try this problem as a review.

Plot $\frac{1}{10}$110 on the number line.

This video looks at comparing fractions using area models.

Which fraction is smaller?

$\frac{2}{6}$26 A$\frac{3}{6}$36 B$\frac{2}{6}$26 A$\frac{3}{6}$36 B

This video shows how to use number lines to compare fractions.

Think about the fractions $\frac{3}{4}$34 and $\frac{4}{5}$45.

Plot the number $\frac{3}{4}$34 on the number line.

Plot the number $\frac{4}{5}$45 on the number line.

The two numbers can be shown on the same number line like this:

Which number is bigger?

$\frac{3}{4}$34

A$\frac{4}{5}$45

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

A$\frac{4}{5}$45

B

What about mixed numbers or improper fractions? This video shows us how to compare using these.

Compare the two fractions by entering the greater than ($>$>) or less than ($<$<) symbol in the box.

$1\frac{8}{9}\editable{}1\frac{4}{9}$189149

Remember!

- The denominator tells us how many equal parts to split the number line into.
- The numerator tells us how many of those equal parts to select.

Count by quarters, halves and thirds, including with mixed numerals. Locate and represent these fractions on a number line
