To convert the number 118 into Roman numerals, we can break it down into its components and then represent each part using Roman numeral symbols. Here’s the step-by-step solution:

### Step 1: Break down the number
We start by breaking down 118 into its components. We can express 118 as:

### Step 3: Write 18 in Roman numerals
Next, we need to convert 18 into Roman numerals. We can break down 18 further:
\[ 18 = 10 + 8 \]
The Roman numeral for 10 is:
\[ X \]
And for 8, we can express it as:
\[ 8 = 5 + 3 \]
The Roman numeral for 5 is:
\[ V \]
And for 3, we can express it as:

### Step 4: Combine the Roman numerals
Now we combine the Roman numerals for 100 and 18:
\[ 118 = C + XVIII \]
So, we write it as:
