2. −0.07
is a
number and would be a
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
