Examples of 1⁄4 as a Percent in Action
Let’s look at some examples to see how 1⁄4 as a percent can be applied in different situations.
Example 1: Calculating a Discount
Imagine you are shopping and find a shirt with a 25% discount. The original price of the shirt is 100. To find the discount amount:</p> <ul> <li>Convert the discount percentage to a decimal: 25% = 0.25</li> <li>Multiply the original price by the decimal: 100 × 0.25 = 25</li> </ul> <p>So, the discount amount is 25, and the final price of the shirt after the discount is $75.
Example 2: Calculating Tax
Suppose you live in a state where the sales tax is 25%. If you purchase an item for 80, the tax amount can be calculated as follows:</p> <ul> <li>Convert the tax percentage to a decimal: 25% = 0.25</li> <li>Multiply the purchase price by the decimal: 80 × 0.25 = 20</li> </ul> <p>The tax amount is 20, so the total cost of the item including tax is $100.
Example 3: Calculating Interest
If you have a savings account with an annual interest rate of 25%, and you deposit 500, the interest earned in one year can be calculated as follows:</p> <ul> <li>Convert the interest rate to a decimal: 25% = 0.25</li> <li>Multiply the deposit amount by the decimal: 500 × 0.25 = 125</li> </ul> <p>The interest earned in one year is 125.
