Answer 1

I can help — a couple items need clarification. Below I’ve answered the ones that are clear and noted what I need for the others.

1) 5
- Type: integer (also whole number, rational)
- Decimal: terminating (5 = 5.0)

2) −0.07
- Type: rational (a negative rational number)
- Decimal: terminating (−0.07 has a finite decimal expansion)

3) 49 4 9 — unclear format
- I’m not sure what this expression is supposed to be. Do you mean 49/49, 49/4, 4/9, 49^(4/9), or something else? Please confirm and I’ll classify it.

4) √99 (square root of 99)
- Type: irrational
- Decimal: non-terminating, non-repeating

5) −0.03521...
- I need to know whether the trailing "..." indicates a repeating pattern (e.g., −0.03521 with a bar over some digits) or simply that the digits continue without repeating. If it is a non-terminating, non-repeating decimal, it is irrational. If it repeats (e.g., −0.03521 03521...), it is rational and repeating. Please specify.

6) √121 (square root of 121) = 11
- Type: integer (also whole number, rational)
- Decimal: terminating (11 = 11.0)

Tell me what 3 is and whether 5 is repeating or non-repeating, and I’ll finish items 3 and 5.
