3 / 0.5 = 6
The common misconseption: divide 5.75 by 2. What you should do is multiply 5.75 by 2, because if you divide something by half it must double, for example when you divide 1 by 0.5, you get 2, this is because there are 2 halves in each 1, which is the concept of division.

5 wholes = ten halves plus one half = 11 halves
When you have 11 halves, you can think of it as having 11 parts, each of which is half of a whole. To find out how many wholes that is, you would divide 11 by 2, since there are 2 halves in a whole. Therefore, 11 halves is equal to 5 wholes with 1 half remaining.
