What subset of real numbers does 18.5 inches belong to?
Julli [10]

Answer:

The correct answer is rational.

Step-by-step explanation:

The diameter of the tree belongs to the subset of rational numbers.

Natural numbers are the numbers 1, 2, 3 4, etc. Since 18.5 has a fractional/decimal component, it is not considered a natural number.  Whole numbers include all of the natural numbers, as well as 0; therefore, 18.5 is not a whole number either.

Integers include all whole numbers as well as negative numbers, but the integer category still does not encompass numbers with a decimal component.  For this reason, 18.5 is not an integer either.

Therefore, the only subset of numbers that 18.5 can fall under is rational numbers.  A rational number is a number that can be represented as a fraction.  18.5 can be represented as 37/2 and is thus a rational number.

You can also refer to the infographic given in the question for further clarity on which subsets of numbers are more inclusive than others.

Hope this helps!

Two equations for a horizontal line could be y = 1 & y = 5
Two equations for a vertical line could be x = 2 & x = 6

Horizontal lines are created when y is always equal to one number, while vertical lines are created when x is always equal to one number.
