Final answer:
The Percent field format shows the percentage value as a decimal, making it useful for computations and comparisons in Mathematics.
Step-by-step explanation:
The Percent field format displays the percentage value as a decimal. When converting a percent to a decimal, you write the value of the percent as a fraction with a denominator of 100 and then divide the numerator by the denominator. For example, to convert 25% to a decimal, you would write 25/100, which is 0.25 as a decimal.
To perform percentage calculations, you take the part divided by the total and multiply by 100. To express a percent with a denominator other than 100 as a decimal, first, convert it to a fraction with a denominator of 100, and then convert it to a decimal. This makes it easier to work with percentage values in mathematical equations and comparisons.
