To evaluate the expression \(\left(\frac{1}{2}\right)^{2}\), we need to raise the fraction \(\frac{1}{2}\) to the power of 2. This involves multiplying \(\frac{1}{2}\) by itself.
Step 1: Define the Fraction
We start with the fraction \(\frac{1}{2}\).
Step 2: Raise the Fraction to the Power of 2
Next, we raise \(\frac{1}{2}\) to the power of 2:
\[
\left(\frac{1}{2}\right)^{2}
\]
Step 3: Perform the Calculation
Performing the calculation, we get:
\[
\left(\frac{1}{2}\right)^{2} = \frac{1}{4} = 0.25
\]
