Final answer:
To find the percent of 100 that is represented by 15, set up a proportion and solve for the unknown percentage.
Step-by-step explanation:
To find the percent of 100 that is represented by 15, you can set up a proportion. Let x be the unknown percentage. The proportion can be written as:
15/100 = x/100
Cross-multiplying gives:
15 * 100 = 100 * x
Simplifying, we have:
x = 15 * 100 / 100
Therefore, x = 15. So, 15% of 100 is 15.
