Understanding Percentages: A Quick Refresher
A percentage is a fraction or ratio expressed as a number out of 100. But the symbol "%" represents "percent," meaning "out of 100. " Take this: 5% means 5 out of 100, which can be written as the fraction 5/100 or the decimal 0.05 Which is the point..
The official docs gloss over this. That's a mistake.
Method 1: Using the Decimal Equivalent
The simplest way to calculate 5% of $500 is to convert the percentage to its decimal equivalent and then multiply it by the total amount Which is the point..
-
Step 1: Convert the percentage to a decimal: Divide the percentage by 100. In this case, 5% / 100 = 0.05
-
Step 2: Multiply the decimal by the total amount: 0.05 * $500 = $25
Because of this, 5% of $500 is $\boxed{$25}$.
Method 2: Using Fractions
Percentages can also be expressed as fractions. 5% can be written as 5/100, which simplifies to 1/20. This method involves multiplying the fraction by the total amount Simple, but easy to overlook. Nothing fancy..
-
Step 1: Express the percentage as a fraction: 5% = 5/100 = 1/20
-
Step 2: Multiply the fraction by the total amount: (1/20) * $500 = $25
This again demonstrates that 5% of $500 is $\boxed{$25}$ Small thing, real impact..
Method 3: Using Proportions
Proportions offer another approach to solving percentage problems. This method sets up a proportion equating the percentage ratio to the ratio of the unknown value to the total amount.
-
Step 1: Set up the proportion: 5/100 = x/$500, where 'x' represents the unknown value (5% of $500).
-
Step 2: Solve for x: Cross-multiply to get 100x = 5 * $500 = $2500
-
Step 3: Divide both sides by 100: x = $2500 / 100 = $25
This method confirms that 5% of $500 is $\boxed{$25}$ Turns out it matters..
