Is–4anirrationalnumber? Choices: (A)yes (B)no

Define irrational numbers: Step 1: Define irrational numbers. Irrational numbers are numbers that cannot be expressed as a fraction of two integers, where the denominator is not zero. They have non-terminating, non-repeating decimal expansions.Analyze number -4: Step 2: Analyze the number -4. -4 is an integer, which means it can be expressed as -4/1, where -4 is the numerator and 1 is the denominator.Determine if -4 is irrational: Step 3: Determine if -4 is irrational. Since -4 can be expressed as a fraction of two integers (as shown in Step 2), it is not an irrational number. It does not have a non-terminating, non-repeating decimal expansion; it's just -4.0 when written as a decimal.

Define irrational numbers: Step $1$ : Define irrational numbers. $\newline$ Irrational numbers are numbers that cannot be expressed as a fraction of two integers, where the denominator is not zero. They have non-terminating, non-repeating decimal expansions.
Analyze number $-4$ : Step $2$ : Analyze the number $-4$ . $\newline$ $-4$ is an integer, which means it can be expressed as $-\frac{4}{1}$ , where $-4$ is the numerator and $1$ is the denominator.
Determine if $-4$ is irrational: Step $3$ : Determine if $-4$ is irrational. $\newline$ Since $-4$ can be expressed as a fraction of two integers (as shown in Step $2$ ), it is not an irrational number. It does not have a non-terminating, non-repeating decimal expansion; it's just $-4.0$ when written as a decimal.
