Answer:
16 rows, 8 seedlings left.
Explanation:
Divide 200 by 12, since 200 seedlings are going to be split in 12 groups in order to fill the rows.
200 ÷ 12 = 16 with a remainder of 8.
The remainder is basically what is left.
Since 12 seedlings are planted in each row, 8 seedlings is not enough to completely fill the row. So, the answer is 16 rows with 8 seedlings left.
