Fraction Line Up

Zearn Grade 4 Mission 5 Lesson 11

Let's Practice creating equivalent fractions and simplifying fractions!

•  $\frac{2}{3}\ x\ \frac{3}{3}=\frac{6}{9}$  

  Tip 1: When creating equivalent fractions you need to multiply your numerator and denominator by the same number. Ex:

• Tip 2: When simplifying fractions you need to divide the numerator and denominatory by the same number. Ex: 

   $\frac{6}{9}\div\frac{3}{3}=\frac{2}{3}$  

Multiple Choice

Which model represents 3/6?

Fill in the Blanks

What is the greatest common factor of 3 & 6?

We can rewrite  $\frac{3}{6}$  using Division

• We can simplify by dividing the numerator and denominator by the greatest common factor

•  $\frac{3}{6}\div\frac{3}{3}$  

Fill in the Blanks

 $\frac{3}{6}\div\frac{3}{3}\equiv$  

Multiple Choice

Which of these number lines represents fifths?

This is how we would label our number line!

Multiple Choice

Which of the number lines represents  $\frac{2}{5}$  decomposed into 4 equal parts? 

Multiple Choice

Which multiplication expression matches the number line on the last slide?

• $\frac{2}{5}\ x\ \frac{2}{2}=\frac{4}{10}$

• $\frac{2}{5}\ x\ \frac{4}{4}=\frac{8}{20}$

Fill in the Blanks

 $\frac{2}{8}\ \div\ \frac{?}{?}=\ \frac{1}{4}$
