Q. Which of the following describe 312? Select all that apply.Multi-select Choices:(A) irrational number(B) rational number(C) real number(D) integer
Calculate Division: Calculate the value of 12/3.12 divided by 3 equals 4.
Check Irrationality: Determine if the result is an irrational number.An irrational number cannot be expressed as a simple fraction or as a terminating or repeating decimal. Since 4 can be expressed as a fraction (14) and does not have an infinite non-repeating decimal expansion, it is not an irrational number.
Verify Rationality: Determine if the result is a rational number.A rational number can be expressed as a fraction where both the numerator and the denominator are integers, and the denominator is not zero. Since 4 can be expressed as 14, it is a rational number.
Confirm Real Number: Determine if the result is a real number.All rational numbers are real numbers. Since 4 is a rational number, it is also a real number.
Identify Integer: Determine if the result is an integer.An integer is a whole number that can be positive, negative, or zero. Since 4 is a whole number without a fractional or decimal part, it is an integer.
