Simplifying fractions

Simplifying fractions

In groups of three:

Use a fraction board to simplify.
1. $\frac{2}{4} = \frac{}{}$
2. $\frac{5}{10} = \frac{}{}$
3. $\frac{6}{8} = \frac{}{}$
Discuss and share with other groups.

Example 2

Simplify:

a) $\frac{4}{12}$

b) $\frac{6}{12}$

c) $\frac{8}{12}$

a) $\frac{4}{12} = \frac{1}{3}$

b) $\frac{6}{12} = \frac{1}{2}$

c) $\frac{8}{12} = \frac{2}{3}$

Note

$\frac{4}{12} = \frac{4 \div 4}{12 \div 4} = \frac{1}{3}$
$\frac{8}{12} = \frac{8 \div 4}{12 \div 4} = \frac{2}{3}$
$\frac{6}{12} = \frac{6 \div 6}{12 \div 6} = \frac{1}{2}$

Exercise B

$\frac{2}{4} = \frac{}{}$
$\frac{6}{9} = \frac{}{}$
$\frac{3}{12} = \frac{}{}$

$\frac{4}{12} = \frac{}{}$
$\frac{6}{8} = \frac{}{}$
$\frac{4}{6} = \frac{}{}$
$\frac{2}{8} = \frac{}{}$

$\frac{9}{12} = \frac{}{}$
$\frac{6}{9} = \frac{}{}$
$\frac{3}{9} = \frac{}{}$
$\frac{10}{12} = \frac{}{}$
