Answer:
200 baseballs
Explanation:
Mike put 400 baseballs into 10 trash bins. He put the same number of baseballs in each bin.
Hence, the number of baseballs he puts in each bin is:
400 / 10 = 40 baseballs
He took 5 trash bins of baseballs. This means that the number of baseballs he took is:
5 * 40 = 200 baseballs
He took 200 baseballs.
