They come in a variety of types. Don't forget that you sometimes have to multiply by $100$ to get it into its final percent form.</p>
<ul>
<li><span style="color:#e74c3c;">Type 1</span>: $30$ is what percentage of $40$?</li>
</ul>
<p>$$\frac{30}{40} \times 100 = 75\%$$</p>
<ul>
<li><span style="color:#e74c3c;">Type 2</span>: What is $32\%$ of $150$?</li>
</ul>
<p>$$\frac{32}{100} \times 150 = 0.32 \times 150 = 48$$ </p>
<ul>
<li><span style="color:#e74c3c;">Type 3</span>: $24$ is $40\%$ of $a$. What is $a$?</li>
</ul>
<p>$$24=\frac{40}{100} \times a$$</p>
<p>$$\frac{24}{0.40}=a$$</p>
<p>$$60=a$$</p>
