What separates the places larger than 1 from those that are fractions of 1 such as tenths hundredths?

Places larger than 1 represent whole units, while places that are fractions of 1, such as tenths and hundredths, denote subdivisions of a single unit. In the decimal system, numbers greater than 1 are positioned to the left of the decimal point, indicating complete values, whereas fractions are found to the right, showing parts of those whole values. For example, 2.5 has 2 (a whole number) and 0.5 (a fraction), illustrating this distinction.
