1. **State the problem:** We have 145 bars of chocolate divided equally among children, each child receiving 3 bars. We need to find the number of children. 2. **Formula used:** To find the number of children, divide the total bars by bars per child: $$\text{Number of children} = \frac{\text{Total bars}}{\text{Bars per child}}$$ 3. **Apply the values:** $$\text{Number of children} = \frac{145}{3}$$ 4. **Simplify the division:** Since 145 is not exactly divisible by 3, we perform the division: $$145 \div 3 = 48 \text{ remainder } 1$$ 5. **Interpretation:** Each child gets 3 bars, so 48 children get 144 bars, and 1 bar remains undistributed. 6. **Final answer:** The number of children who received 3 bars each is **48**.
