Greatest to least 56.2,56.32,56.321

56.321 > 56.32 > 56.2.

Explanation:

A number line is the straight line in which number is represented along a straight line in a fixed interval. A number line can be extended infinitely and it can be extended in either negative direction or in positive direction.

In the given situation when we represent 56.2, 56.32, and 56.321 on the number line the number 56.2 lies on the left most side then 56.32 and after that number 56.321 lies means it is the order of increasing magnitude.

Therefore the pattern from the greatest to least lies as 56.321 > 56.32 > 56.2.
