<h1 class="center">Convert Fractions to Decimals</h1>
<div style="background: url(numbers/images/hdr-screws-tape.jpg) no-repeat; width: 100%; height: 100px; background-position: center center;"></div>
<h3>The simplest method is to use a calculator.</h3>
<p>Just divide the top of the fraction by the bottom, and read off the answer!</p>
<div class="example">
<h3>Example<i>:</i> What is <span class="intbl">
<em>5</em>
<strong>8</strong>
</span> as a decimal ... ?</h3>
<p style="float:left; margin: 0 10px 5px 0;"><a href="scientific-calculator.html"><img src="images/calculator.gif" alt="calculator" height="97" width="76"></a></p>
<p class="center larger">... get your calculator and type in "5 / 8 ="</p>
<p>The answer should be <b>0.625</b></p>
</div>
<h3>No Calculator? Use <a href="long_division3.html">Long Division to Decimal Places</a></h3>
<div class="example">
<h3>Example: here is what long division of <span class="intbl">
<em>5</em>
<strong>8</strong>
</span> looks like:</h3>
<br>
<div class="mono">
&nbsp;&nbsp;&nbsp;<span style="border-bottom: 1px solid;"> 0.625</span><br>
&nbsp;8 )5.000<br>
&nbsp;&nbsp;&nbsp;&nbsp;<span style="border-bottom: 1px solid;">0</span><br>
&nbsp;&nbsp;&nbsp;&nbsp;5.0<br>
&nbsp;&nbsp;&nbsp;&nbsp;<span style="border-bottom: 1px solid;">4.8</span><br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;20<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<span style="border-bottom: 1px solid;">16</span><br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;40<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<span style="border-bottom: 1px solid;">40</span><br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0
</div>
<p>In that case we inserted extra zeros and did <span class="intbl"> <em>5.000</em> <strong>8</strong> </span> to get <b>0.625</b></p>
<p>Read the <a href="long_division3.html">Long Division to Decimal Places</a> page for more details.</p>
</div>
<h2>Another Method</h2>
<h3>Yet another method you may like is to follow these steps:</h3>
<ul>
<li><b>Step 1</b>: Find a number you can multiply by <b>the bottom of the fraction</b> to make it 10, or 100, or 1000, or any <font color="blue">1 followed by 0s</font>.</li>
<li><b>Step 2</b>: Multiply both top and bottom by that number.</li>
<li><b>Step 3</b>. Then write down just the top number, putting the decimal point in the correct spot (one space
from the right hand side for every zero in the bottom number)</li>
</ul>
<div class="example">
<h3>Example: Convert <span class="intbl">
<em>3</em>
<strong>4</strong>
</span> to a Decimal</h3>
<p>Step 1: We can multiply 4 by <span class="large">25</span> to become 100</p>
<p>Step 2: Multiply top and bottom by 25:</p>
<div class="clear">
<table class="larger" align="center" cellspacing="5" cellpadding="0" border="0">
<tbody>
<tr style="text-align:center;">
<td colspan="3"><b>×25</b></td>
</tr>
<tr style="text-align:center;">
<td colspan="3"><img src="images/style/arrow-rt-over.svg" alt="right over arrow" height="25" width="75"></td>
</tr>
<tr class="larger" align="center">
<td><span class="intbl">

<strong>4</strong>

<td>&nbsp;=&nbsp;</td>
<td><span class="intbl">

</tr>
<tr style="text-align:center;">
<td colspan="3"><b>×25</b></td>
</tr>
</tbody></table>
</div>
<p>Step 3: Write down 75 with the decimal point 2 spaces from the right (because 100 has 2 zeros);</p>
<p class="center large">Answer = 0.75</p>
</div>
<div class="example">
<h3>Example: Convert <span class="intbl">
<em>3</em>
<strong>16</strong>
</span> to a Decimal</h3>
<p>Step 1: We have to multiply 16 by <b>625</b> to become 10,000</p>
<p>Step 2: Multiply top and bottom by 625:</p>
<div class="clear">
<table class="larger" align="center" cellspacing="5" cellpadding="0" border="0">
<tbody>
<tr style="text-align:center;">
<td colspan="3"><b>×625</b></td>

<strong>16</strong>
</span></td>
<td>&nbsp;=&nbsp;</td>
<td><span class="intbl">
<em>1,875</em>
<strong>10,000</strong>
</span></td>
</tr>
<tr style="text-align:center;">

</tr>
<tr style="text-align:center;">
<td colspan="3"><b>×625</b></td>
</tr>
</tbody></table>
</div>
<p>Step 3: Write down 1875 with the decimal point 4 spaces from the right (because 10,000 has 4 zeros);</p>
<p class="center"><span class="large">Answer = 0.1875</span></p>
</div>
<div class="example">
<h3>Example: Convert <span class="intbl">
<em>1</em>
<strong>3</strong>
</span> to a Decimal</h3>
<p>Step 1: There is no way to multiply 3 to become 10 or 100 or any "1 followed by 0s", but we can calculate an <b>approximate</b> decimal by choosing
to multiply by, say, 333</p>
<p>Step 2: Multiply top and bottom by 333:</p>
<div class="clear">
<table class="larger" align="center" cellspacing="5" cellpadding="0" border="0">
<tbody>
<tr style="text-align:center;">
<td colspan="3"><b>×333</b></td>
</tr>
<tr style="text-align:center;">
<td colspan="3"><img src="images/style/arrow-rt-over.svg" alt="right over arrow" height="25" width="75"></td>
</tr>
<tr class="larger" align="center">
<td><span class="intbl">
<em>1</em>
<strong>3</strong>
</span></td>
<td>&nbsp;=&nbsp;</td>
<td><span class="intbl">
<em>333</em>
<strong>999</strong>
</span></td>
</tr>
<tr style="text-align:center;">
<td colspan="3"><img src="images/style/arrow-rt-under.svg" alt="right under arrow" height="25" width="75"></td>
</tr>
<tr style="text-align:center;">
<td colspan="3"><b>×333</b></td>
</tr>
</tbody></table>
</div>
<p>Step 3: Now, <b>999 is <i>nearly</i> 1,000</b>, so let us write down 333 with the decimal point 3 spaces from the right (because 1,000 has 3 zeros):</p>
<p class="center large">Answer = 0.333 (accurate to only 3 decimal places !!)</p>
