Convert the following rational numbers into decimals:
`(1)/(2)`

Answer

To convert the rational number \( \frac{1}{2} \) into a decimal, we can follow these steps:

### Step 1: Set up the division
We need to divide 1 by 2. This can be written as:
\[ 1 \div 2 \]

### Step 2: Add a decimal point and a zero
Since 1 is smaller than 2, we cannot divide directly. Therefore, we add a decimal point and a zero to 1, making it 1.0. This allows us to perform the division:
\[ 1.0 \div 2 \]

### Step 3: Perform the division
Now we can divide:
- 2 goes into 10 five times (because \( 2 \times 5 = 10 \)).
- Write down 5 after the decimal point.

### Step 4: Subtract
Now, subtract 10 from 10:
\[ 10 - 10 = 0 \]

### Step 5: Write the final answer
Since there are no remainders, the division is complete. Thus, we can conclude:
\[ \frac{1}{2} = 0.5 \]

### Final Answer
The decimal representation of \( \frac{1}{2} \) is \( 0.5 \).
