if a number is not a rational number, then it is______.
A. an integer
B.an irrational
C.whole number
D.a radical
My best answer is B. Can you check please
@Ms.Sue
the -ir prefix means "not"
I agree.
Annabelle, u r correct, B is right, Thanks!
^_^
Yes, your answer is correct. If a number is not a rational number, it is an irrational number.
To determine the correct answer, we need to understand the definitions of each option:
A. An integer is a number that can be either positive, negative, or zero, without any fractional or decimal parts. Examples of integers are -3, 0, and 7.
B. An irrational number is a number that cannot be expressed as a fraction or a ratio of two integers. Examples of irrational numbers are π (pi) and √2 (square root of 2).
C. A whole number is a number that is greater than or equal to zero and does not have any fractional or decimal parts. Examples of whole numbers are 0, 1, 2, and 3.
D. A radical refers to the square root or any other root of a number. It is a mathematical symbol (√) used to represent such roots.
Since the question asks for the option that describes a number that is not rational, we can eliminate options A, C, and D. The only remaining option is B, which correctly identifies that a number that is not rational is an irrational number.
