Which of the following formulas correctly calculates the conversion of a fraction to a decimal?

The formula that accurately calculates the conversion of a fraction to a decimal is obtained by dividing the numerator by the denominator. When you have a fraction, the numerator represents the number of parts you have, and the denominator represents the total number of equal parts. By performing the division, you find out how many times the denominator fits into the numerator, which expresses the fraction as a decimal.

For example, in the fraction 3/4, dividing 3 (the numerator) by 4 (the denominator) gives 0.75, demonstrating the decimal equivalent of the fraction. This process is fundamental in mathematics and allows for easier interpretation and manipulation of numerical values in various applications.

The other options do not reflect the proper method for converting a fraction to a decimal, as they either involve addition or subtraction, which do not relate to the mathematical operation needed for conversion.
