Answer 1

A placeholder in digits is a zero used to hold a place in a larger numeral. It is not a significant digit but is used to indicate the position of other digits.

Step-by-step explanation:

A placeholder in digits is a zero used to hold a place in a larger numeral. It is not a significant digit but is used to indicate the position of other digits. For example, in the number 1,205, the zero is a placeholder indicating that there is no digit in the hundreds place. The zeros in this number are not significant but are necessary for the number's correct representation.
