Questions
How do I calculate my marks percentage?
Divide the marks you scored by the total marks and multiply by 100. For example, 430 out of 500 is 430 ÷ 500 × 100 = 86%.
How do I work out X% of a number?
Multiply the number by X and divide by 100. For example, 18% of 250 is 250 × 18 ÷ 100 = 45.
How do I find a percentage increase or decrease?
Subtract the old value from the new one, divide by the old value and multiply by 100. Going from 40 to 50 is (50 − 40) ÷ 40 × 100 = a 25% increase.
