1. **State the problem:** We need to find the cost of six bowls of rice minus two bowls, then divide that result by two. 2. **Identify the cost per bowl:** One bowl costs 250. 3. **Calculate the cost of six bowls:** $$6 \times 250 = 1500$$ 4. **Calculate the cost of two bowls:** $$2 \times 250 = 500$$ 5. **Subtract the cost of two bowls from six bowls:** $$1500 - 500 = 1000$$ 6. **Divide the result by two:** $$\frac{1000}{2} = 500$$ **Final answer:** The cost of six bowls minus two bowls divided by two is 500.
