<p class="center"><b><i>Equivalent Fractions</i></b><i> have the same value, even though they may look different.</i></p>
<p>These fractions are really the same:</p>
<p class="center large"><span class="intbl">
<em>1</em>
<strong>2</strong>
</span>&nbsp; = &nbsp;<span class="intbl">
<em>2</em>
<strong>4</strong>
</span>&nbsp; = &nbsp;<span class="intbl">
<em>4</em>
<strong>8</strong>
</span></p>
<p><b>Why are they the same?</b> Because when you multiply or divide <b>both</b> the top and bottom by the same number, the fraction keeps it's value.</p>
<p>The rule to remember is:</p>
<p class="center larger"><i>"Change the bottom using multiply or divide,<br>
And the same to the top must be applied"</i></p>
<p>Here is why those fractions are really the same:</p>

<p>Choose the number you divide by carefully, so that the results (both top and bottom) stay <a href="whole-numbers.html">whole numbers</a>.</p>

<li>You can make equivalent fractions by multiplying or dividing <b>both top and bottom</b> by the same amount.</li>
<li>You only multiply or divide, <b>never add or subtract</b>, to get an equivalent fraction.</li>
