If a place value is missing a number, the correct response is to add a zero. This is because adding a zero in the missing place value maintains the value of the number while ensuring the correct number of digits for calculations.

To solve \(-18.1 - 5\):

  1. When you subtract a positive number (5) from a negative number (-18.1), you essentially add the absolute values and keep the negative sign.
  2. So, \(-18.1 - 5 = -18.1 - 5 = -23.1\).

Therefore, the correct answer is −23.1 (negative 23.1).
