Short Answer 
To round the number 88000 to the nearest thousandth, identify that the thousand’s place is 0 and the hundred’s place is also 0. Since the hundred’s place is less than 5, you keep 88000 unchanged, resulting in a rounded number of 88000.
Step 1: Identify the Number
Start by identifying the number that you want to round. In this case, the number is 88000. Understanding the current value is crucial, as it serves as the basis for rounding to the nearest thousandth.
Step 2: Determine the Rounding Rule
To round a number to the nearest thousandth, look at the digit in the thousand’s place, which is the third digit from the right. For 88000, this digit is 0. If the next digit (the hundred’s place) is less than 5, you keep the thousand’s place digit the same; if it is 5 or more, you increase the thousand’s place digit by one.
Step 3: Apply the Rounding
For the number 88000, the hundred’s place is also 0, which is less than 5. Therefore, the rounding rule indicates that you keep 88000 the same. As a result, the rounded number to the nearest thousandth is still 88000.
