Kevin is planting 15 bushes and 9 trees in rows if he wants all the rows the same with no plants left over what is the greatest number of rows kevin can plant

he could do 6 row of 4, 8 rows of 3, 12 rows of 2

Step-by-step explanation:
15+9=24
6*4=24
8*3=24
12*2=24

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
