What arrangment of movable and fixed pulleys would give a mechanical advantage of 3?

To achieve a mechanical advantage of 3 using pulleys, you can use a combination of fixed and movable pulleys. One common arrangement is to have one fixed pulley and one movable pulley. In this setup, the load is attached to the movable pulley, which is supported by a fixed pulley above it. The user would pull down on the rope, effectively distributing the weight of the load over three segments of rope, resulting in a mechanical advantage of 3.
