<h3>What are Percentages?</h3>
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the money raised by Nina in the first month is $800, while the money raised by Nina in the second month is 20% more.
Therefore, the money raised by Nina in the second month is,
Money raised = $800 + 20% of $800
= $800 + 0.20($800)
