Three-Dimensional is the property of the space in which we live and move that indicates motion can take place in three mutually perpendicular directions.
Three-dimensional is often expressed with three-dimensional coordinates.
In physics and mathematics, the dimension of a mathematical space or object is informally defined as the minimum number of coordinates needed to specify any point within that space. Mostly we use two dimensional space or three dimensional space. A flat plane or shape is two-dimensional has two dimensions known are length and width. In three dimensions we take length and width and height.
15 into thirds would be 15 divided by three. This would be 5. If you take 14 and divide it in half you get 7. Then subtract 5 from 7 and you get 2. The answer is 2.
