3. Jamail collects 3 bags of sand that weigh 13 pounds, 14 pounds, and 17 pounds. He puts an equal amount of the sand into 4 small aquariums. How many pounds of sand did Jamail put into each aquarium?

Step 1 ：First, we need to find the total weight of the sand that Jamail collected. This can be done by adding the weights of the three bags of sand together: \(13 + 14 + 17 = 44\) pounds.

Step 2 ：After finding the total weight, we can then divide this by the number of aquariums to find out how much sand Jamail put into each aquarium: \(\frac{44}{4} = 11\) pounds.

Step 3 ：Final Answer: Jamail put \(\boxed{11}\) pounds of sand into each aquarium.
