Calculating Percentages

A percentage quantifies a number as a fraction out of 100.
To determine a percentage of a number:
[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]
Converting a percentage to a decimal involves dividing by 100:
[ \text{Decimal} = \frac{\text{Percentage}}{100} ]

Percentage Increase/Decrease

Percentage Increase measures growth:
[ \text{Percentage Increase} = \left( \frac{\text{New Value} - \text{Original Value}}{\text{Original Value}} \right) \times 100 ]
Percentage Decrease measures a reduction:
[ \text{Percentage Decrease} = \left( \frac{\text{Original Value} - \text{New Value}}{\text{Original Value}} \right) \times 100 ]

Rates of Change

A rate of change reflects how a quantity alters concerning another quantity.
Average Rate of Change is calculated as:
[ \text{Rate of Change} = \frac{\text{Change in Value}}{\text{Change in Time}} ]
Widely applied across fields like economics, physics, and biology to track trends over time.

Applications of Percentages

Used in Finance for calculating discounts, sales tax, and price markup.
In Statistics, percentages analyze survey data, proportions, and demographic studies.
Health statistics utilize percentages for measuring incidence and prevalence.
In Education, percentages assist in grading, GPA calculations, and assessing performance metrics.

Interest Rates

Interest rates represent the percentage earned or paid on a loan/investment over time.
Simple Interest is calculated with:
[ \text{Simple Interest} = \text{Principal} \times \text{Rate} \times \text{Time} ]
Compound Interest grows on both principal and accumulated interest, calculated as:
[ A = P \left(1 + \frac{r}{n}\right)^{nt} ]
- In this equation, ( A ) = total amount, ( P ) = principal, ( r ) = annual interest rate, ( n ) = frequency of interest application, ( t ) = number of periods.
Interest rates are crucial for making informed financial decisions regarding investments, loans, and savings.
