Chapter 1 - Section 1.6 - Complex Numbers - 1.6 Exercises: 12

Answer

The real part of -1/2 is -1/2 and the imaginary part is 0.

Work Step by Step

Complex numbers are written in the form a+bi, with a being the real number and b being the imaginary number. Since there is no "i" in this number, b must be equal to zero, because i*0 = 0. Therefore, -1/2 must be a, so -1/2 is the real part and 0 is the imaginary part.
