How is a percentage converted into a decimal fraction?

A percentage is a way of expressing a number as a fraction of 100. To convert a percentage into a decimal, you need to express that fraction in a form that does not involve the percentage sign.

When you select the option to move the decimal point two places to the left, you effectively transform the percentage into a decimal form. For example, 25% becomes 0.25 when you move the decimal point two places left. This process is grounded in the understanding that "percent" literally means "per hundred," so moving the decimal point two places left reflects that you're transforming a per-hundred value into a simple decimal fraction.

Other methods for conversion would not yield the correct decimal. For instance, simply multiplying by 10 does not accurately convert a percentage to a decimal; it would actually increase the number rather than decrease it to its decimal value. Subtracting 10 from the percentage does not relate to conversion to a decimal and would misrepresent the original value. Adding a decimal before the percentage also fails to convert the percentage itself into a decimal; you'd still be left with a percentage expressed in a non-standard form.

Thus, moving the decimal point two places to the left is the correct and systematic way to convert a percentage into a
