Understanding Percentages

A percentage is a fraction of 100. For example, 7% means 7 out of 100, or 7/100. To find a percentage of a number, we convert the percentage to a decimal and then multiply.

Method 1: Converting to a Decimal

2. Multiply by the original amount: Now, multiply the decimal (0.07) by the original amount ($20.00): 0.07 x $20.00 = $1.40

Therefore, 7% of $20.00 is $1.40

Method 2: Using Fractions

1. Convert the percentage to a fraction: 7% can be written as the fraction 7/100.

2. Multiply by the original amount: Multiply the fraction (7/100) by the original amount ($20.00): (7/100) x $20.00 = $1.40

Therefore, 7% of $20.00 is $1.40 using the fraction method as well.

Real-World Applications

Understanding how to calculate percentages is essential for many situations. For example:

• Discounts: If a store offers a 7% discount on a $20.00 item, you would subtract $1.40 from the original price.

• Tips: Calculating a 7% tip on a $20.00 meal involves the same calculation.
