Subject | Subject

Some text here about the topic of discussion

Multiple Choice

Select the number sentence that is true

$\frac{3}{5}<\frac{4}{5}$

$\frac{3}{5}>\frac{4}{5}$

$\frac{3}{5}=\frac{4}{5}$

Same Numerator

Subject | Subject

Multiple Choice

Select the number sentence that is true.

$\frac{3}{4}<\frac{3}{10}$

$\frac{3}{4}>\frac{3}{10}$

$\frac{3}{4}=\frac{3}{10}$

Strategy - Number Lines

Example 1

Strategy: Number Lines

Step 2

Some text here about the topic of discussion

Multiple Choice

Select the number sentence that is true.

$\frac{2}{3}<\frac{7}{12}$

$\frac{2}{3}=\frac{7}{12}$

$\frac{2}{3}>\frac{7}{12}$

Same Numerator

Some text here about the topic of discussion

Multiple Choice

$\frac{5}{10}\ldots\ \frac{5}{8}$

Multiple Choice

$\frac{4}{6}\ldots\ \frac{4}{8}$

Same Denominator

If a fraction has the same denominator. The number with the greater numerator is the greater number.

Rad

Same Denominator

To make it easier to compare fractions you can also change each fraction to have the same denominator. Once the fractions have the same denominator the number with the greater numerator is the greater number.

Cross Multiply

One of the easiest ways to compare fractions is to cross multiply. To cross multiply you will multiply the numerator of the first number to the denominator of the second and vice versa

Some text here about the topic of discussion

Cross Multiply

Some text here about the topic of discussion

Multiply the numerator 3 by the denominator 7 and get 21. Write that above the three because that is the numerator used. Then multiply the numerator 4 by the denominator 8 and get 32.

Cross Multiply
