<h2>The Simplest Method is to Use a Calculator</h2>

<table align="center" cellpadding="5" border="0">

<p>Steps:</p>
|
||
<ul>
|
||
<li>Divide the top of the fraction by the bottom,</li>
|
||
<li>Then multiply the result by 100 and read off the answer !</li>
|
||
</ul></td>
|
||
</tr>
|
||
</tbody></table>
|
||
<div class="example">
|
||
<h3>Example: What is <span class="intbl">
|
||
<em>5</em>
|
||
<strong>8</strong>
|
||
</span> as a percent?</h3>
|
||
<p>Get your calculator and type in "5 ÷ 8 =", the calculator should show <b>0.625</b></p>
|
||
<p>Then multiply by 100 and your answer is: <b>62.5%</b></p>
|
||
<p>(Remember to put the "%" sign so people know it is "per 100")</p>
|
||
</div>
|
||
<p>OR you can multiply the top by 100 first then divide by the bottom number:</p>
|
||
<div class="example">
|
||
<h3>Example: What is <span class="intbl">
|
||
<em>5</em>
|
||
<strong>8</strong>

||
<p>Multiply 5 by 100 first, then divide by 8</p>
|
||
<p class="center large">500 ÷ 8 = 62.5%</p>
|
||
<p>(Remember that "%" sign!)</p></div>
|
||
<h2>Or Move the Decimal 2 Places</h2>
|
||
<p>After dividing, instead of multiplying by 100 we can just <b>move the decimal point 2 places to the right</b>, then add the %</p>
|
||
<div class="example">
|
||
<h3>Example: Convert <span class="frac"><sup>1</sup>/<sub>8</sub></span> to a percentage</h3>
|
||
<p>Divide 1 by 8:</p>
|
||
<p class="center large">1 ÷ 8 = 0.125</p>
|
||
<p>Move the decimal point <b>2 places to the right</b></p>
|
||
<p class="center"><img src="numbers/images/decimal-to-percent.svg" alt="decimal to percent"></p>
|
||
<p>Remember to add the "%" sign: <b>12.5%</b></p>

</div>
|
||
|
||
<h2>Another (Harder) Method</h2>
|
||
Percent means "per 100", so try to change the fraction to <span class="larger"><span class="intbl">
|
||
<em>?</em>
|
||
<strong>100</strong>
|
||
</span></span> form.

<h3 align="center">Answer = 18.75%</h3>
|

</div>
|
||
<h2>Yet Another Method: Proportions</h2>
|
||
<p>Because a percent is actually a ratio (parts per 100) we can also use <a href="algebra/proportions.html">Proportions</a> to do the conversion.</p>
|
||
<p>First, put what you know into this form:</p>
|
||
<p class="center larger"><span class="intbl">
|
||
<em>Top of Fraction</em>
|
||
<strong>Bottom of Fraction</strong>
|
||
</span> = <span class="intbl">
|
||
<em>Percent</em>
|
||
<strong>100</strong>
|
||
</span></p>
|
||
<p>Then solve using <b>"multiply across the known corners, divide by the third number"</b>:</p>
|
||
<div class="example">
|
||
<h3>Example: Convert <span class="intbl">
|
||
<em>3</em>
|
||
<strong>16</strong>
|
||
</span> to percent</h3>
|
||
<p>Fill in what you know:</p>
|
||
<p class="center larger"><span class="intbl">
|
||
<em>3</em>
|
||
<strong>16</strong>
|
||
</span> = <span class="intbl">
|
||
<em>Percent</em>
|
||
<strong>100</strong>
|
||
</span></p>
|
||
|
||
<p>Multiply across the known corners, then divide by the third number. The "known corners" are top left and bottom right:</p>
|
||
<p class="center larger">Percent = (3 × 100) / 16<br>
|
||
= 300 / 16<br>
|
||
= <b>18.75%</b></p>
|
||
<h3>Answer: <span class="intbl">
|
||
<em>3</em>
|
||
<strong>16</strong>
|
||
</span> is <b>18.75%</b> (same answer as the previous example!)</h3>
