Understanding Percentages
A percentage is a way of representing a portion of a whole as a fraction out of 100. The symbol "%" is used to denote percentages. For example, 50% means 50 out of every 100, which is equivalent to the fraction 50/100 or 1/2.
Calculating the Percentage
To find out what percentage of 40 is 26, we can use the following steps:
-
Set up a proportion: We know that 26 is a part of 40. We can write this as a proportion:
- 26/40 = x/100 where x represents the unknown percentage.
-
Cross-multiply: Multiply the numerator of the first fraction (26) by the denominator of the second fraction (100) and vice versa. This gives us:
- 26 * 100 = 40 * x
-
Solve for x: Simplify the equation:
- 2600 = 40x
- x = 2600 / 40
- x = 65
Therefore, 26 is 65% of 40.
Examples
Here are a couple of real-world scenarios where understanding percentages is helpful:
- Sales Discounts: A store offers a 20% discount on a $100 item. The discount amount is 20/100 * $100 = $20.
- Interest Rates: A bank offers a 3% annual interest rate on a savings account. If you deposit $1,000, you'll earn 3/100 * $1000 = $30 in interest per year.
