Is4arationalnumber? Choices: (A)yes (B)no

Define rational number: Step 1: Define a rational number. A rational number can be expressed as the fraction p/q, where p and q are integers and q is not zero.Express 4 as fraction: Step 2: Express 4 as a fraction. 4 can be written as 4/1, where both 4 and 1 are integers, and 1 is not zero.Check validity of 4/1: Step 3: Check if 4/1 meets the criteria for a rational number. Since 4 and 1 are integers and 1 is not zero, 4/1 is a valid fraction representing a rational number.

Define rational number: Step $1$ : Define a rational number. $\newline$ A rational number can be expressed as the fraction $\frac{p}{q}$ , where $p$ and $q$ are integers and $q$ is not zero.
Express $4$ as fraction: Step $2$ : Express $4$ as a fraction. $\newline$ $4$ can be written as $\frac{4}{1}$ , where both $4$ and $1$ are integers, and $1$ is not zero.
Check validity of $\frac{4}{1}$ : Step $3$ : Check if $\frac{4}{1}$ meets the criteria for a rational number. $\newline$ Since $4$ and $1$ are integers and $1$ is not zero, $\frac{4}{1}$ is a valid fraction representing a rational number.
