👉 Percentage math is a fundamental concept used to express ratios or proportions as parts of a whole, typically showing how much of a part is related to the entire quantity. It's calculated by dividing the part (the numerator) by the whole (the denominator), then multiplying by 100 to convert it into a percentage. For example, if you have 75 out of 100 items, the percentage is (75/100)
100 = 75%. This helps in understanding proportional relationships, such as sales growth, discounts, or population changes, by showing how much an increase or decrease represents of the original amount.
