Round off the number 970.02 to one decimal place.

Answer

To round off the number 970.02 to one decimal place, we follow these steps:

### Step 1: Identify the digit in the first decimal place.
The number is 970.02. The digit in the first decimal place (the first digit after the decimal point) is 0.

### Step 2: Look at the digit in the second decimal place.
The digit in the second decimal place (the second digit after the decimal point) is 2.

### Step 3: Apply the rounding rule.
According to the rounding rules:
- If the digit in the second decimal place is less than 5, we do not change the digit in the first decimal place.
- If the digit in the second decimal place is 5 or greater, we increase the digit in the first decimal place by 1.

In this case, since the second decimal place is 2 (which is less than 5), we keep the first decimal place (0) as it is.

### Step 4: Write the rounded number.
Thus, when we round off 970.02 to one decimal place, we get 970.0.

### Final Answer:
The rounded number is **970.0**.
