Formula for Percentage Calculation:

Percentage= (Total Part) x 100 

Part: This is the number or value you want to calculate the percentage of.  
 

• Total: This is the whole or total number or amount in relation to which you want to find the percentage.

Example

Imagine you received a score of 45 on an exam where the total score was 60 and you want to calculate the percentage.

1. Identify the Part and Total:
   Part = 45 (the score you achieved) 

   • Total = 60 (the total score)

2. Substitute into the equation:

  (45/60)×100=75%

Therefore you received a score of 75%.
