Q. The number s is rational. Which statement about s−2 is true?Choices:(A) s−2 is rational.(B) s−2 is irrational.(C) s−2 can be rational or irrational, depending on the value of s.
Identify nature of s: Identify the nature of the number s.s is a rational number, which means it can be expressed as a fraction of two integers, where the denominator is not zero.
Determine nature of 2: Determine the nature of the number 2. The number 2 is an integer, which is also a rational number because it can be expressed as 12.
Analyze s−2: Analyze the operation s−2.Subtracting a rational number from another rational number will always result in a rational number. This is because the subtraction of two fractions (or integers) is another fraction (or integer).
Conclude nature of s−2: Conclude the nature of s−2. Since both s and 2 are rational, their difference s−2 is also rational.
