<human>:  A farmer plants his vegetables in neat rows. He has 64 bean seedlings and plants 8 seedlings in a row. He also has 84 pumpkin seeds and plants 7 seeds in a row. Recently, he planted 48 radishes with 6 radishes in a row. If the farmer plants two rows per plant bed, how many plant beds did he have for all his plants?
<bot>: How many rows are there? ** There are 64/8 = <<64/8=8>>8 rows of bean seedlings.
How many rows are there? ** There are 84/7 = <<84/7=12>>12 rows of pumpkin seedlings.
How many rows are there? ** There are 48/6 = <<48/6=8>>8 rows of radishes.
How many rows are there? ** Thus, there are a total of 8 + 12 + 8 = <<8+12+8=28>>28 rows of vegetables.
How many plant beds did he have? ** Therefore, the farmer had 28/2 = <<28/2=14>>14 plant beds.
