The number b is rational. Which statement about b - 6 is true? Choices: (A)b - 6 is rational. (B)b - 6 is irrational. (C)b - 6 can be rational or irrational, depending on the value of b.

Understand nature of b: Understand the nature of the number b. Since b is given as a rational number, it can be expressed as the quotient of two integers, where the denominator is not zero.Analyze b - 6: Analyze the operation b - 6. Subtracting a rational number b by an integer 6 (which is also a rational number since it can be expressed as 6/1) will result in another rational number because the difference of two rational numbers is always rational.Conclude nature of b - 6: Conclude the nature of b - 6. Since both b and 6 are rational, their difference b - 6 is also rational. This is true regardless of the specific value of b, as long as b is rational.

Understand nature of $b$ : Understand the nature of the number $b$ . Since $b$ is given as a rational number, it can be expressed as the quotient of two integers, where the denominator is not zero.
Analyze $b - 6$ : Analyze the operation $b - 6$ . $\newline$ Subtracting a rational number $b$ by an integer $6$ (which is also a rational number since it can be expressed as $\frac{6}{1}$ ) will result in another rational number because the difference of two rational numbers is always rational.
Conclude nature of $b - 6$ : Conclude the nature of $b - 6$ . Since both $b$ and $6$ are rational, their difference $b - 6$ is also rational. This is true regardless of the specific value of $b$ , as long as $b$ is rational.
