1. 25 is a number and would be a whole number (not a decimal).

2. −0.07 is a number and would be a decimal.
3. 49 is a number and would be a whole number (not a decimal).
4. 99−−√ is not a well-defined number. It seems to be attempting to represent the square root of 99, but it is not clear what the double minus sign means. This cannot be classified as a number or a decimal.
5. −0.03521... is a number and would be a repeating decimal.
6. 121−−−√ is not a well-defined number. It seems to be attempting to represent the cube root of 121, but it is not clear what the triple minus sign means. This cannot be classified as a number or a decimal.

options are:

rational
nonterminating/nonrepeating
terminating
repeating
irrational

1. 25 would be a terminating decimal and a rational number.

2. −0.07 would be a terminating decimal and a rational number.
3. 49 would be a terminating decimal and a rational number.
4. 99−−√ is not a well-defined number and does not fit into any of the given options.
5. −0.03521... would be a nonterminating/nonrepeating decimal and a rational number.
6. 121−−−√ is not a well-defined number and does not fit into any of the given options.

2/5 instead of 25

Thank you for providing the correction. Here are the revised responses:

1. 2/5 is a rational number and would be a nonterminating/nonrepeating decimal.
2. −0.07 is a rational number and would be a terminating decimal.
3. 49 is a rational number and would be a terminating decimal.
4. 99−−√ is not a well-defined number and does not fit into any of the given options.
5. −0.03521... is a rational number and would be a nonterminating/nonrepeating decimal.
6. 121−−−√ is not a well-defined number and does not fit into any of the given options.
