2 ½ is called a mixed number (a whole number and a fraction), not complex.
Complex number means there can be real and/or imaginary parts to a number. Without confusing you though, complex numbers include all of the real numbers (which include all fractions and mixed numbers).
No. It's a plain old mixed number .
The conjugate of a complex number is obtained by changing the sign of its imaginary part. The complex number -2 can be expressed as -2 + 0i, where the imaginary part is 0. Therefore, the conjugate of -2 is also -2 + 0i, which simplifies to -2. Thus, the conjugate of the complex number -2 is -2.
This is best done if the complex number is in polar coordinates - that is, a distance from the origin, and an angle. Take the square root of the argument (the absolute value) of the complex number; and half the angle.
No, it is not.
An expression for half of a number can be represented mathematically as ( \frac{x}{2} ), where ( x ) is the original number. This indicates that the number is being divided by 2, resulting in its half. For example, if the number is 10, half of it would be ( \frac{10}{2} = 5 ).

2
Half the number.
To calculate one-half of any number, divide the number by 2.
No, it is not.
A number is divided into Half by dividing the whole number by 2.for example, divide 8 into half.. so the answer will be 8/2 = 4
Half of a number is the result of dividing the number by 2. In this case, half of 31 is 31 divided by 2, which equals 15.5.

No. Taking one half of a number is the same as dividing it by 2. If you divide a number by 1/2 that's the same as multiplying it by 2.
The complex number of the equation z = x + iy is x.
