Question

Identify the set of numbers that best describes each situation. Explain your choice. Example 3: The markings on a standard ruler.

A) Natural numbers: Whole numbers used for counting and indicating order.
B) Rational numbers: Numbers that can be expressed as fractions or ratios.
C) Integers: Whole numbers, their opposites, and zero.
D) Irrational numbers: Numbers that cannot be expressed as fractions.

Answer 1

The markings on a standard ruler can be described by the set of integers.

Step-by-step explanation:

The set of numbers that best describes the markings on a standard ruler is C) Integers: Whole numbers, their opposites, and zero.

The markings on a standard ruler represent lengths, which are whole numbers and can be positive or negative depending on the direction of measurement. For example, if you measure from the zero mark to the 2-inch mark, the length is 2 inches. If you measure in the opposite direction from the zero mark to the -2-inch mark, the length is -2 inches.

Therefore, integers are the most appropriate set of numbers to describe the markings on a standard ruler.
