Show Answer Key & Explanations Step-by-step solution for: Classifying Real Numbers: Mystery Pattern
Since I can't view or access images directly, I’ll help you solve the problem based on your description.

You're given a grid of numbers and asked to classify each number as rational, irrational, integer, or whole. Then, you’re to color-code them according to a key (which you haven’t provided), but we can work through the classification step by step.

Let’s go over the definitions first:

Definitions:


- Whole numbers: 0, 1, 2, 3, ... (non-negative integers)
- Integers: ..., -3, -2, -1, 0, 1, 2, 3, ... (includes negatives)
- Rational numbers: Numbers that can be written as a fraction \( \frac{p}{q} \) where \( p \) and \( q \) are integers and \( q \neq 0 \). Includes terminating decimals and repeating decimals.
- Irrational numbers: Cannot be written as a fraction; non-repeating, non-terminating decimals (e.g., \( \pi \), \( \sqrt{2} \)).

Now let's analyze some of the values in the grid. Since I don’t have the image, I’ll assume you’ve provided a list or table similar to this:

> Example values:
> 0.3, -14.0, 3, √1.25, 1.23, √7, π, 8.143..., etc.

We’ll go through each one and classify it.

Step-by-step Classification:



1. 0.3
→ Terminating decimal → Rational
→ Not an integer, not whole

2. -14.0
→ Same as -14 → Integer → Rational
→ Not whole (negative)

3. 3
→ Integer, Whole, Rational

4. √1.25
→ 1.25 = 5/4 → √(5/4) = √5 / 2 → √5 is irrational → So this is irrational

5. 1.23
→ Terminating decimal → Rational

6. √7
→ Not a perfect square → Irrational

7. π
→ Famous irrational number → Irrational

8. 8.143...
→ If it's non-repeating and non-terminating (like 8.143143143...) then it could be rational if repeating, but if it's random like 8.143… with no pattern, it might be irrational. But since it's written as "8.143..." without dots indicating repetition, likely irrational unless specified. However, if it's just 8.143 (terminating), then rational.

Assuming it's meant to be non-repeating → Irrational

9. √64
→ √64 = 8 → Integer → Whole → Rational

10. √2
→ Irrational

11. 0.4
→ Terminating → Rational

12. √145
→ 145 not a perfect square → Irrational

13. -√8
→ √8 = 2√2 → irrational → so -√8 is also irrational

14. -10.1
→ Decimal → Rational

15. 3.6
→ Rational

16. 0.4
→ Rational

17. √21
→ Not a perfect square → Irrational

18. -1.4
→ Rational

19. 7.83
→ Rational

20. √33
→ Not a perfect square → Irrational

---

Now, let’s look at more from the grid:

- -64 → Integer → Rational
- 300 → Whole → Integer → Rational
- √209 → Not perfect square → Irrational
- -34 → Integer → Rational
- 1.4 → Rational
- -8.2 → Rational
- → π is irrational → any non-zero multiple of π is irrational → Irrational
- 6.81 → Rational
- 12½ → 12.5 → Rational
- 0.87 → Rational
- -√121 → √121 = 11 → -11 → Integer → Rational
- 75 → Whole → Integer → Rational
- -1.5 → Rational
- -√144 → √144 = 12 → -12 → Integer → Rational
- 20/3 → Fraction → Rational
- √12 → √(4×3) = 2√3 → Irrational
- -√100 → √100 = 10 → -10 → Integer → Rational
- -4√7 → √7 is irrational → scalar multiple → Irrational
- √64 → 8 → Integer → Rational
- -132 → Integer → Rational
- 7.43 → Rational
- -√4 → √4 = 2 → -2 → Integer → Rational
- -0.2 → Rational
- -48 → Integer → Rational
- 4√1 → √1 = 1 → 4×1 = 4 → Integer → Rational
- √9 → 3 → Integer → Rational
- 3.36 → Rational
- 85 → Whole → Integer → Rational
- -√5 → Irrational
- 121 → Whole → Integer → Rational
- 7 → Whole → Integer → Rational
- 63 → Whole → Integer → Rational
- 4.4 → Rational
- 15m → If m is variable? But probably typo. Maybe meant 15? Assume 15 → Whole → Integer → Rational
- 5/3 → Rational
- √22 → Not perfect square → Irrational
- π → Irrational
- 0 → Whole → Integer → Rational
- 0.75 → Rational
- → 0 → Whole → Integer → Rational
- √10 → Irrational
- → Irrational
- 625 → Whole → Integer → Rational
- √5 → Irrational
- -√8 → Irrational
- -10.1 → Rational
- 3.6 → Rational
- 0.4 → Rational
- √21 → Irrational
- -1.4 → Rational
- 7.83 → Rational
- √33 → Irrational

Summary of Classifications:

|--------|---------|
| 0.3 | Rational |
| -14.0 | Rational, Integer |
| 3 | Rational, Integer, Whole |
| √1.25 | Irrational |
| 1.23 | Rational |
| √7 | Irrational |
| π | Irrational |
| 8.143... | Irrational (if non-repeating) |
| √64 | Rational, Integer, Whole |
| √2 | Irrational |
| 0.4 | Rational |
| √145 | Irrational |
| -√8 | Irrational |
| -10.1 | Rational |
| 3.6 | Rational |
| √21 | Irrational |
| -1.4 | Rational |
| 7.83 | Rational |
| √33 | Irrational |

And so on for the rest.

How to Color the Key:



Assume you have a color key like:

- Red → Irrational
- Blue → Rational (but not integer)
- Green → Integer (but not whole)
- Yellow → Whole

Or something similar. You’d use the colors accordingly.

For example:

- π → Irrational → Red
- 3 → Whole → Yellow
- -14 → Integer (not whole) → Green
- 0.3 → Rational (not integer) → Blue
- √2 → Irrational → Red

---

Final Advice:



Go through each cell in your grid and apply these rules:

1. Is it a whole number? (0, 1, 2, 3, ...)
- Yes → Whole → Color accordingly
2. Is it an integer? (includes negative whole numbers)
- Yes → Integer
3. Can it be written as a fraction?
- Yes → Rational
- No → Irrational

Remember:
- All integers are rational.
- All whole numbers are integers and rational.
- Any root that isn't a perfect square/cube/etc. is irrational.
- π, e, √2, √3, etc. are irrational.

If you can provide the exact list of numbers or describe the grid clearly, I can give you a full colored classification.

But based on typical such problems, you now have the method!
