Understanding the Formula:

The basic formula for calculating percentages is \(P = \frac{Part}{Whole} \times 100\), where \(P\) is the percentage, \(Part\) is the portion of the total, and \(Whole\) is the total amount.


How do you calculate the percentage increase from 50 to 75?
Use the formula \(\frac{New Value - Original Value}{Original Value} \times 100\% = \frac{75-50}{50} \times 100\% = 50\%\).
What is 25% of 200?
Apply the formula \(P = \frac{Part}{Whole} \times 100\), so \(25\%\) of 200 is \(\frac{25}{100} \times 200 = 50\).
How to convert a percentage to a fraction?
Divide the percentage by 100 and simplify if necessary. For example, \(60\% = \frac{60}{100} = \frac{3}{5}\).
How to calculate CGPA?
CGPA is calculated by dividing the total number of grade points earned in all subjects by the total number of subjects.
How to calculate percentage without a calculator?
To calculate percentage without a calculator, use the percentage formula and simplify the fractions manually.
Why do we calculate percentage?
Percentages are calculated to compare quantities of different sizes in a uniform way, making it easier to understand proportions and ratios.
