Load "L" is attached to the movable pulley. A rope is fixed at a point in ceiling that passes through the movable pulley.
In order to lift the load "L" by "X" meters, the effort "E" needs to travel the distance of 2X meters. (The entire rope needs to be pulled by "E" for a distance of 2X.)
Now, Velocity Ratio equals (Distance traveled by "E") divided by (Distance traveled by "L")
So it becomes : 2X/X. This equals to 2
Since it is a ratio. it has no units of measurement.

What is the mechanical advantage a single movable pulley?
E=l/2 2=l/e or l/e=2 ma =l/e ma of single moveable pulley is : l/e=2
What is a single moveable pulley?
A simple single pulley enables the applied force to change direction. A pulley at the top of a well is the common example. In many applications, such as the fan belt on a car, it is used to transfer energy from one shaft to another.
