Express of the complex number in the form `a + i b`.
`(1/5+i2/5)-(4+i5/2)`

Explanation

To express the complex number \((\frac{1}{5} + i\frac{2}{5}) - (4 + i\frac{5}{2})\) in the form \(a + ib\), we will follow these steps:

### Step 1: Write the expression clearly
We start with the expression:
\[ \left(\frac{1}{5} + i\frac{2}{5}\right) - \left(4 + i\frac{5}{2}\right) \]
