Here is how you can fill in the response areas based on the given numbers:
- 2/5 is a rational number and would be a terminating decimal.
- -0.07 is a rational number and would be a terminating decimal.
- 4/9 is a rational number and would be a non-terminating repeating decimal.
- V--99 (assuming this is a negative number with a variable, like -99) is a rational number and would be a terminating decimal (if we consider -99.0).
- -0.03521 is a rational number and would be a terminating decimal.
- V--121 (assuming this is another negative number, like -121) is a rational number and would be a terminating decimal (if we consider -121.0).
Feel free to adjust the terms if the context of "V--" has a specific meaning that alters the classification of those numbers.
