Round off :
1.732 , correct to 1 decimal place

Answer

To round off the number 1.732 to one decimal place, follow these steps:

### Step-by-Step Solution:

1. **Identify the Decimal Places**:
The number 1.732 has three decimal places: 7 (tenths), 3 (hundredths), and 2 (thousandths).

2. **Determine the Decimal Place to Round To**:
We need to round to one decimal place, which is the first digit after the decimal point. In this case, it is 7.

3. **Look at the Next Decimal Place**:
The next decimal place after 7 is 3 (the hundredths place).

4. **Apply the Rounding Rule**:
According to the rounding rule:
- If the digit in the next decimal place (hundredths place) is 5 or greater, you increase the tenths place by 1.
- If it is less than 5, you leave the tenths place as it is.

Here, since the digit is 3 (which is less than 5), we do not increase the tenths place.

5. **Write the Final Rounded Number**:
Therefore, the number rounded to one decimal place is 1.7.

### Final Answer:
1.7
