Question

1. which describes the two parts of a measurement? a unit and a symbol a number and a unit a symbol and a conversion factor a conversion factor and a number

Explanation:

A measurement needs a numerical value to show the quantity and a unit to define what is being measured. For example, \(5\) meters has the number \(5\) and the unit meter. A symbol is just a representation of a unit (like \(m\) for meter), not a separate part. A conversion factor is used to change from one unit to another and is not part of the basic measurement.

Answer:

a number and a unit
