Understanding Percentages: The Basics
Before diving into the specifics of "3 of 100.00," let’s refresh our memories about percentages. A percentage represents a fraction out of 100. For example, when you express a number as a percentage, you are conveying how many parts of 100 it constitutes.
Example Breakdown:
- If you have 50 out of 100, that is 50%.
- If you only have 3 out of 100, that is 3%.
The phrase “3 of 100.00” literally translates to 3 percent of 100.00.
Mathematical Representation:
To determine what 3 of 100.00 means mathematically, you can use the following formula:
[
\text{Part} = \left( \frac{\text{Percent}}{100} \right) \times \text{Whole}
]
In this case, it becomes:
[
\text{Part} = \left( \frac{3}{100} \right) \times 100.00 = 3.00
]
Thus, 3 of 100.00 simply equals 3.
