A bottle holds 12 liters of water. Each jug can hold 4 liters. How many jugs are needed to fill the bottle exactly?

Step-by-step solution

1. Write the equation $4x=12$ where $x$ is the number of jugs.
2. Solve for $x$ by dividing both sides by 4: $x=\frac{12}{4}$.
3. Simplify the fraction: $x=3$.
4. Thus, 3 jugs are needed.
