                    <p>Rewrite the decimal as a fraction with a denominator of 100.</p>
                    <p><code><var>DECIMAL</var> = \dfrac{<var>PERCENT</var>}{100}</code></p>

                </div>
                <p>Another way to convert a decimal to a percent is to multiply by <code>100</code> (or move the decimal two places to the right) and add a percent sign.</p>
