Answer

The real part of the complex number -2/3i is 0 and the imaginary part is -2/3.

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 "a" in this complex number, a must be equal to zero. Therefore, b has to be -2/3, so the real part is 0 and the imaginary part of -2/3.
