Answer:
9 rows, each having 3 tomato plants, 5 bean plants, and 6 carrot plants.
Explanation:
This requires the GCF, or the greatest common factor. This means that you need the largest whole number that divides evenly into each of the numbers (27, 45, and 54).
27, 45, and 54 can all be divided by 9 to get a whole number.
27/9=3
45/9=5
54/9=6
This means that in each row, there will be 3 tomato plants, 5 bean plants, and 6 carrot plants.
