Step-by-Step Worked Explanation
In plain English: In this formula, X is the part being measured and Y is the whole it's compared against. Dividing X by Y converts the relationship into a decimal fraction (for example, taking a part of 30 out of a whole of 200 gives 30 ÷ 200 = 0.15); multiplying by 100 rescales that fraction onto a base of 100 (0.15 × 100 = 15%), which is exactly what the word 'percent' means - it comes from the Latin phrase per centum, 'per hundred,' a usage that dates back to Roman tax and commerce records long before modern algebraic notation existed. Because the formula only depends on the ratio between X and Y, it applies identically whether they represent dollars, exam scores, or population counts.
