Real-time calculations

Step-by-step solving

1. Initial ratio relationship is given as: A : B = 4 : 6
2. Simplify by dividing by the Greatest Common Divisor (GCD):
- Simplified baseline ratio = 2 : 3
3. Set up the equivalent proportion equation:
- 4 / 6 = 12 / x
4. Cross-multiply to solve for x:
- x = (12 × 6) / 4
- x = 72 / 4 = 18

Student-friendly explanations

"A ratio is like a recipe ingredient list. If a recipe needs 4 cups of flour for every 6 cups of sugar, the ratio is 4:6. If you scale the recipe up to use 12 cups of flour, you must scale up the sugar proportionally to 18 cups to keep the taste identical!"
