decimal.

3. 4/9
is a
number and would be a
decimal.

4. 99−−√
is a
number and would be a
decimal.

5. −0.03521...
is a
number and would be a
decimal.

6. 121−−−√
is a
number and would be a
decimal.

Answer 1

Let's fill in the blanks for each statement:

1. 2/5 is a rational number and would be a terminating decimal (since 2 divided by 5 equals 0.4).

2. −0.07 is a rational number and would be a terminating decimal.

3. 4/9 is a rational number and would be a repeating decimal (since 4 divided by 9 equals approximately 0.4444..., which repeats).

4. 99−−√ (the square root of 99) is an irrational number and would be a non-terminating, non-repeating decimal (approximately 9.949).

5. −0.03521... is a rational number and would be a non-terminating repeating decimal (if the '...' indicates that it continues the pattern of decimal digits).

6. 121−−−√ (the square root of 121) is a rational number and would be a terminating decimal (since the square root of 121 equals 11).

In summary:

1. rational, terminating decimal
2. rational, terminating decimal
3. rational, repeating decimal
4. irrational, non-terminating non-repeating decimal
5. rational (or non-terminating repeating decimal, depending on the context), non-terminating repeating decimal
6. rational, terminating decimal
