Ratios compare two numbers like a : b. If we multiply both parts by the same number, we get an equivalent ratio. This calculator generates lots of them instantly, useful for practice, homework, and real-world tasks (recipes, scale drawings, maps).
What does the calculator do?
- Enter a ratio (a and b). Integers, decimals, and fractions (like
3/4) are allowed. - Choose how many results to generate.
- Set a starting multiplier and step size.
- Optionally simplify each result.
- Copy any row or the whole table.
Example: For 3 : 4, with 6 results (start=1, step=1), you get: - ×1 → 3 : 4
- ×2 → 6 : 8
- ×3 → 9 : 12
- ×4 → 12 : 16
- ×5 → 15 : 20
- ×6 → 18 : 24
With simplification on, all reduce back to 3 : 4.
Why is it important?
- In school: Strengthens proportional reasoning.
- In real life: Cooking, maps, model scaling, comparing speeds.
- In advanced math: Foundation for fractions, percentages, algebra.
