If a place value is missing a number, you should add a zero in that place value.
If a place value is missing a number, the correct answer is to add a zero in the corresponding place. When we write numbers, each digit's position represents a place value, such as ones, tens, hundreds, and so on. If a number is missing a digit, adding a zero in that place ensures that the value of the number remains accurate. For example, if the number is 305 and the tens place is missing, you would add a zero and write it as 3005.
