Answer :

Let’s solve the given problem step-by-step.

We have the fraction [tex]\(\frac{1}{2}\)[/tex].

Step 1: Calculate the square of the fraction [tex]\(\frac{1}{2}\)[/tex].

Step 2: To square a fraction, you square the numerator and the denominator separately:

[tex]\[ \left( \frac{1}{2} \right)^2 = \frac{1^2}{2^2} = \frac{1}{4} \][/tex]

Step 3: Convert the fraction to its decimal form to verify the answer:

[tex]\[ \frac{1}{4} = 0.25 \][/tex]

So, the square of [tex]\(\frac{1}{2}\)[/tex] is [tex]\(0.25\)[/tex] which is also [tex]\(\frac{1}{4}\)[/tex].

Therefore, the correct answers are:
- 0.25
- [tex]\(\frac{1}{4}\)[/tex]
