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 consists of a numerical value (number) that quantifies the amount and a unit that defines what is being measured. For example, in "5 meters", 5 is the number and meters is the unit. A symbol is just a shorthand for a unit (e.g., m for meters), a conversion factor is used to change from one unit to another (e.g., 100 cm = 1 m), and they are not the two fundamental parts of a measurement.

Answer:

a number and a unit
