$\frac{1}{2} - 2 i = \frac{- 4 i + 1}{2}$

Explanation

\frac{1}{2} - 2 i \overset{◯}{1} \frac{- 4 i + 1}{2}

①

Subtract $2 i$ from $\frac{1}{2}$ to get $\frac{- 4 i + 1}{2}$ .

Step 1: Write $2 i$ as a fraction by putting $1$ in the denominator.

Step 2: To subtract raitonal expressions, both fractions must have the same denominator.
We can create a common denominator by multiplying the second fraction by $2$ .

\frac{1}{2} - 2 i Step 1 \frac{1}{2} - \frac{2 i}{1} = \frac{1}{2} - \frac{2 i \cdot 2}{1 \cdot 2} = Step 2 \frac{1}{2} - \frac{4 i}{2} = \frac{- 4 i + 1}{2}
