Answer

To express the given decimals as percentages, we will follow a systematic approach. Here’s the step-by-step solution:

### Step 1: Understand the Concept
To convert a decimal to a percentage, we multiply the decimal by 100.

### Step 2: Convert Each Decimal

#### Part i: Convert 0.16 to Percentage
1. **Multiply by 100**:
\[ 0.16 \times 100 = 16 \]
2. **Write the percentage**:
\[ 0.16 = 16\% \]

#### Part ii: Convert 3.6 to Percentage
1. **Multiply by 100**:
\[ 3.6 \times 100 = 360 \]
2. **Write the percentage**:
\[ 3.6 = 360\% \]

#### Part iii: Convert 0.05 to Percentage
1. **Multiply by 100**:
\[ 0.05 \times 100 = 5 \]
2. **Write the percentage**:
\[ 0.05 = 5\% \]

#### Part iv: Convert 2.39 to Percentage
1. **Multiply by 100**:
\[ 2.39 \times 100 = 239 \]
2. **Write the percentage**:
\[ 2.39 = 239\% \]

### Final Answers:
- \( 0.16 = 16\% \)
- \( 3.6 = 360\% \)
- \( 0.05 = 5\% \)
- \( 2.39 = 239\% \)
