In the formula Xml x %, converting the percentage to a decimal is necessary for accurate calculations. Percentages are typically expressed as parts per hundred, which means that in order to use them mathematically in formulas, they need to be transformed into a form that reflects this relationship.

To convert a percentage to a decimal, you divide the percentage by 100. For example, 25% becomes 0.25 when converted to a decimal because 25 ÷ 100 = 0.25. This conversion allows you to properly perform multiplication and other mathematical operations with the percentage as part of the equation.

Leaving it as is, changing it to a whole number, or multiplying by 100 would not yield the correct numerical relationship for calculations involving percentages. Therefore, changing the percentage into a decimal format is the correct approach when performing calculations in this context.
