A field is 3.9 mi^2 is being subdivided into 1.3x10^3 family gardens. How many square miles will there be in each garden?
To find out how many square miles there will be in each garden, we need to divide the total area of the field by the number of family gardens.
The total area of the field is 3.9 mi^2.
The number of family gardens is 1.3x10^3.
Therefore, each garden will have an area of 3.9 mi^2 / 1.3x10^3 = 0.003 mi^2.
