A square field that is 1/4 mile long and 1/4 mile wide has area
[tex] \dfrac{1}{4} \cdot \dfrac{1}{4} = \dfrac{1}{16} [/tex]
So, to know how many of these fields fit in the biggest field, you have to divide their areas:
[tex] \dfrac{1}{\frac{1}{16}} = 16 [/tex]
So, if the farmer divides his land into square fields that are 1/4 mile long and 1/4 mile wide, he will have 16 of these smaller fields.
