Nancy bought a pie sliced it into 8 pieces. She gave 1/2 to Joe and Darcy, and she gave 1/4 to Carl. How many slices were left? Give me reasons, before answering the question
The total number of slices she gave to Joe and Darcy is 1 / 2 x 8 = 4. The total slice she gave to Carl is 1 / 4 x 8 = 2. Therefore, the total slices left is 8 - 4 - 2 = 2. So the final answer is 2.
