A farmer has 1 mile*1mile of field he divided into 1/3 how many fields in total he will have

Answer 1

If you mean that he divided it into 1/3 * 1/3 chunks, then there are 9 small fields.

But you just say he divided it into 1/3, which to means that he made 3 small fields.

Once you decide just what you mean, I'm sure you can figure it out. If not, try drawing a diagram!! See what you get!
