Decimal
A decimal is an alternative notation for a fraction whose denominator is a power of ten (such as , , , and so on). Instead of writing the denominator explicitly, the position of each digit after a decimal point indicates which power of ten it represents. For example, and . This place-value system for parts smaller than one mirrors the way whole numbers use place value for parts larger than one, making decimals a natural extension of the base-ten number system.

A logistics coordinator records the weights of outgoing shipments using a digital scale that displays values as decimals (e.g., 0.75 kg). True or False: According to the base-ten number system, a decimal is an alternative notation for a fraction whose denominator is a power of ten (such as 10, 100, or 1,000).
Defining Decimal Notation in Technical Documentation
A quality control technician is calibrating a high-precision digital sensor used to measure the thickness of protective coatings. The sensor displays values to four decimal places. To correctly document the calibration results in the technical log, the technician must identify the place values in their proper sequence. Arrange the following decimal place-value names in the correct order, starting from the position immediately to the right of the decimal point and moving further to the right.
