Round off :
9.638 , correct to 2 decimal places

Answer

To round off the number 9.638 to two decimal places, we follow these steps:

### Step 1: Identify the decimal places
The number 9.638 has three decimal places:
- The first decimal place (tenths) is 6.
- The second decimal place (hundredths) is 3.
- The third decimal place (thousandths) is 8.

### Step 2: Determine the rounding point
We need to round off to two decimal places, which means we focus on the second decimal place (3 in this case) and look at the digit in the third decimal place (8).

### Step 3: Apply rounding rules
According to rounding rules:
- If the digit in the next decimal place (third decimal place) is 5 or greater, we add 1 to the digit in the second decimal place.
- If it is less than 5, we leave the second decimal place as it is.

Since the third decimal place is 8 (which is greater than 5), we will add 1 to the second decimal place (3).

### Step 4: Calculate the new value
- The second decimal place (3) becomes 3 + 1 = 4.
- The first decimal place (6) remains the same.

### Step 5: Write the final rounded number
Combining these, the rounded number is 9.64.

### Final Answer:
The number 9.638 rounded off to two decimal places is **9.64**.
