Yes, mechanical advantage doesn't need to be a gear type which you can always count the ratio of teeth to a full number. A pulley type gear can be of a fraction in gear ratio.

==========================

Think of a Class-1 lever ... like a see-saw ... that's 5 feet long,

with the fulcrum 2 feet from one end:

-- When the effort is applied to the longer side, the MA is 11/2 .

-- When the effort is applied to the shorter side, the MA is 2/3 .
