Answer:
25%
Explanation:
To solve this problem, a proportion would be the easiest way to find a solution. First, set up one side of your proportion with the two numbers given: 18 and 72. These will be written in a fraction format, which will look like this:
(with p representing part and w representing the whole)
Next, set up the right side of your proportion. We know that percents will always be out of 100%, so this number will be our whole. Since we are looking for the percent out of 100-- the part --we will need to use x to represent this value. The proportion should now look like this:
To solve, just cross multiply and divide! First, multiply the 18 by the 100, giving you 1,800. Next, divide the 1,800 by 72, giving you a final answer of 25%! 25% of the candies are chocolate. Please let me know if you have any questions! :)
