Answer: 20%
<em>Step by Step Explanation: </em>
<em>Start by subtracting 519.29 from 649, you would get 129.8</em>
<em>Then take 129.8 and divide that by 649.</em>
<em>You get 0.2 which equals 20%</em>
<em>Tip: To find the percent of a fraction you divide the numerator by the denominator. For example, if you want to find the percent on a test, and you get a 8/10 you just divide 8 by 10. Which obviously equals 80.</em>
