Final Answer:
The image shows a 3D layered model for teaching rational numbers, designed as a Class 8 math project. The layers represent different number sets: whole numbers at the bottom, integers in the middle, and rational numbers on top — visually demonstrating how each set contains the one below it. Small cards with examples (like fractions, decimals, negative numbers) are attached to show what belongs in each category.
This is not a problem to solve numerically — it’s a visual educational tool. If you’re being asked to “solve” something related to this, you may need to:
1. Identify which layer a given number belongs to (e.g., -5 → integers; 0.75 → rational numbers).
2. Explain why rational numbers include all integers and whole numbers.
3. Create your own version of this model using paper or craft materials.
Since no specific question was asked beyond showing the image, here’s the key takeaway:
✔ Rational numbers = any number that can be written as a fraction p/q where q ≠ 0. This includes:
- Whole numbers (like 0, 1, 2…)
- Integers (like -3, -2, -1, 0, 1, 2…)
- Fractions (like ½, -¾)
- Terminating decimals (like 0.25)
- Repeating decimals (like 0.333…)
So if your homework says “use this model to classify these numbers,” just match them to the correct layer!
Example classification:
- 4 → Whole Number / Integer / Rational
- -2 → Integer / Rational
- ⅔ → Rational only
- 0.6 → Rational only
You’ve got this! 🎓

Final Answer:
This is a 3D educational model illustrating the hierarchy of number sets: Whole Numbers ⊂ Integers ⊂ Rational Numbers. Use it to classify numbers by placing them on the correct tier based on their type. No numerical answer required — it’s a conceptual learning aid.
Parent Tip: Review the logic above to help your child master the concept of 8 number projects.
