Although Ancient Romans used Roman numerals I, V, X, L, and so on, calculations were often performed in fractions that were divided by 100. It was equivalent to the computing of percentages that we know today. Computations with a denominator of 100 became more standard after the introduction of the decimal system.

💡 The percentage difference calculator takes care of a very similar concept, used when we don’t know the direction of the calculation (from number A to B or B to A). The best way to solve this is by finding the GCF (greatest common factor) of the numerator and denominator and dividing both of them by GCF. This step is optional and can be customized based on your requirements.

In this case, the whole is the total number of children in the school. While it’s certainly quick and painless just to use our percentage calculator, you don’t always have access to a computer or a smartphone.
