To determine what to do if a place value is missing a number, we need to understand the concept and rules of place value. The place value system is a way of representing numbers based on the position of digits within a number.
In this case, if a place value is missing a number, we can use the concept of zero as a placeholder. The correct answer to the question is:
D. Add a zero
When a place value is missing a number, we can add a zero in that position to maintain the correct value and place of each digit. This ensures that the number retains its intended meaning and value.
For example, if we have the number 205 and the tens place value is missing a number, we would add a zero to represent it properly as 2005.
So, to address a missing number in a place value, we add a zero in that position.
