**Planting
the trees
**

A farmer bought 21 peach trees from the
nursery and wants to plant them in rows of 6 trees each. Because 6 is
his lucky number he wants as many rows of 6 as he can make. The more
6 row trees the more times his lucky number is applied. What is the
maximum number of rows he will be to plant, making sure there are 6
trees in every row? (hint:
it is more than 3 rows) |
