Answer
Real part= $2.3$
Imaginary part= $-4.9$
Work Step by Step
A complex number is written as $a+bi$, where $a$ is the real part and $b$ is the imaginary part as it is multiplied to the imaginary unit $i$.
Since the complex number is $2.3-4.9i$, $2.3$ represents the real part while $-4.9$ represents the imaginary part.
