Turn marks obtained into a percentage in one step.
Marks to percentage formula
Percentage = marks obtained ÷ total marks × 100
Example: 432 out of 500 is 432 ÷ 500 × 100 = 86.4%.
Adding up several subjects
Add the marks of every subject first, then add the maximum marks, then divide. Do not average the subject percentages if the subjects have different maximum marks, because that gives the wrong answer.
Example: 78/100, 41/50 and 135/150 give (78 + 41 + 135) ÷ (100 + 50 + 150) × 100 = 254 ÷ 300 × 100 = 84.67%.
