Define irrational number: Step 1: Define an irrational number. An irrational number cannot be expressed as a simple fraction, meaning it cannot be written as a ratio of two integers. Irrational numbers have non-terminating, non-repeating decimal expansions.Analyze number -7: Step 2: Analyze the number -7. -7 is an integer, which means it can be expressed as -7/1, where both -7 and 1 are integers.Determine if -7 is irrational: Step 3: Determine if -7 fits the definition of an irrational number.

Define irrational number: Step $1$ : Define an irrational number. $\newline$ An irrational number cannot be expressed as a simple fraction, meaning it cannot be written as a ratio of two integers. Irrational numbers have non-terminating, non-repeating decimal expansions.
Analyze number $-7$ : Step $2$ : Analyze the number $-7$ . $-7$ is an integer, which means it can be expressed as $-7/1$ , where both $-7$ and $1$ are integers.
Determine if $-7$ is irrational: Step $3$ : Determine if $-7$ fits the definition of an irrational number. $\newline$ Since $-7$ can be expressed as a ratio of two integers ( $-7$ and $1$ ), it is not an irrational number; it is a rational number.
