To convert a decimal to a percentage, you multiply the decimal by 100. Let's apply this step-by-step method to the decimal 0.2.
1. Identify the decimal: We start with the given decimal, which is [tex]\( 0.2 \)[/tex].
2. Multiply by 100: To convert the decimal to a percentage, multiply [tex]\( 0.2 \)[/tex] by [tex]\( 100 \)[/tex]:
[tex]\[
0.2 \times 100 = 20
\][/tex]
3. Add the percentage symbol: The result is [tex]\( 20 \)[/tex].
Therefore, [tex]\( 0.2 \)[/tex] as a percentage is [tex]\( 20\% \)[/tex].
So, the correct answer is:
(C) [tex]\( 20\% \)[/tex].
