Q. Which of the following describe −2? Select all that apply.Multi-select Choices:(A) rational number(B) integer(C) real number(D) irrational number
Check Rational Number: Step 1: Determine if −2 is a rational number.Rational numbers are numbers that can be expressed as a fraction where both numerator and denominator are integers, and the denominator is not zero. −2 can be written as −2/1.
Check Integer: Step 2: Check if −2 is an integer.Integers include all whole numbers and their negative counterparts, including zero. −2 fits this definition.
Check Real Number: Step 3: Determine if −2 is a real number.Real numbers include all rational and irrational numbers. Since −2 is rational, it is also a real number.
Check Irrational Number: Step 4: Check if −2 is an irrational number.Irrational numbers cannot be expressed as a simple fraction. −2, as shown earlier, can be expressed as −2/1, which is a simple fraction.
