Q. The number t is rational. Which statement about t−10 is true?Choices:(A) t−10 is rational.(B) t−10 is irrational.(C) t−10 can be rational or irrational, depending on the value of t.
Identify Number 10: Identify the nature of the number 10. 10 is an integer, which is also a rational number since it can be expressed as a fraction(10/1).
Properties of Rational Numbers: Understand the properties of rational numbers. Subtracting a rational number from another rational number always results in a rational number. This is because the set of rational numbers is closed under subtraction.
Apply Property to Expression: Apply the property to the given expression.Since t is rational and 10 is rational, their difference (t−10) must also be rational.
Conclude Expression Nature: Conclude the nature of the expression t−10. The statement about t−10 being rational is true, regardless of the value of t, as long as t is rational.
