To convert a percentage to a decimal, divide the percentage by 100. For the given percentage, 120%, divide 120 by 100 to get the decimal equivalent. The second number, 0.12, is already in decimal form.
Step 1: Convert Percentage to Decimal
To convert \( 120\% \) to a decimal, we use the formula:
\[
\text{Decimal} = \frac{120}{100} = 1.2
\]
Step 2: Identify the Decimal Value
The second value given is \( 0.12 \), which is already in decimal form.
Final Answer
The decimal equivalent of \( 120\% \) is \( 1.2 \) and the second decimal value is \( 0.12 \). Thus, the answers are:
\[
\boxed{1.2} \quad \text{and} \quad \boxed{0.12}
\]
