Understanding Percentages

What is a Percentage?

A percentage is a way of expressing a number as a fraction of 100. It is denoted by the percent sign (%). The term "percent" comes from the Latin per centum, meaning "by the hundred." Percentages are used to compare ratios, determine proportions, and express how large or small one quantity is relative to another. For example, if you score 70% on a test, it means you answered 70 out of every 100 questions correctly. Percentages are versatile and widely used because they provide a common basis for comparison across different contexts and scales.

Converting Percentages to Decimals and Fractions

To work with percentages mathematically, it's often necessary to convert them into decimal form or fractions:

• Decimal Form: Divide the percentage by 100.
Example: 70% = 70 ÷ 100 = 0.70
• Fraction Form: Write the percentage as a fraction with denominator 100, then simplify if possible.
Example: 70% = 70/100 = 7/10 Understanding these conversions is crucial when performing calculations involving percentages. ---

Percent Increase and Percent Decrease

Understanding how to calculate the change in a quantity relative to its original value is essential in many fields.
• Percent Increase:
\[ \text{Percent Increase} = \frac{\text{New Value} - \text{Original Value}}{\text{Original Value}} \times 100 \]
• Percent Decrease:
\[ \text{Percent Decrease} = \frac{\text{Original Value} - \text{New Value}}{\text{Original Value}} \times 100 \]

Calculating Percentages in Different Contexts

• Finding What Percentage One Number is of Another:
\[ \text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100 \]
• Solving for the Part or Whole:
Rearranged formulas allow solving for unknowns when given percentages.

Real-Life Example: Applying 70% of a Quantity

Suppose a store offers a 70% discount on an item priced at $60. To find the discount amount:
• Convert 70% to decimal: 0.70
• Multiply by the original price:
0.70 × $60 = $42 The discount amount is $42, so the sale price is:
• $60 - $42 = $18
This practical example illustrates how understanding percentages directly impacts financial decisions. ---
