<h1>JFractionLab - Help</h1>
<!-- Titel of Chapter-->
<h2>Multiplying fractions</h2>
<!-- Content of Chapter -->
<h3>Explanation:</h3>
One question, asked in two different ways:<br>
<ul>
<li>"What is the half of two thirds?"<br>oder</li>
<li>"What are two thirds divided by two?"</li>
</ul>
<table>
<tr>
<td>
<IMG src="multiply-pizzas/2o3.png" width="139" height="138" align="left" border="0">
</td>
<td>
<IMG src="multiply-formulas/2o3-times-1o2_problem.png" width="117" height="87" align="left" border="0">
</td>
</tr>
<tr>
<td>
<IMG src="multiply-pizzas/2o6.png" width="137" height="136" align="left" border="0">
</td>
<td>
<IMG src="multiply-formulas/2o3-times-1o2_solution.png" width="107" height="93" align="left" border="0">
</td>
</tr>
</table>
So you simply divide the field into two halfs and then count the number of fields in one half.<br>
<br>
Another example: <br>
What are two thirds of three fifths?
<table>
<tr>
<td>
<IMG src="multiply-pizzas/3o5.png" width="140" height="138" align="left" border="0">
</td>
<td>
<IMG src="multiply-formulas/3o5-times-2o3_problem.png" width="125" height="89" align="left" border="0">
</td>
</tr>
<tr>
<td>
<IMG src="multiply-pizzas/6o15.png" width="138" height="136" align="left" border="0">
</td>
<td>
<IMG src="multiply-formulas/3o5-times-2o3_solution.png" width="112" height="84" align="left" border="0">
</td>
</tr>
</table>
You divide the field into three rows of the same size and count the number of fields in two of them!<br>

<h3>Steps:</h3>
<ul>
<li>Multiply the numerators</li>
<li>Multiply the denominators</li>
</ul>

This is what it would look like in the JFractionLab.<br>
