1)   MA = d2/d1   always  as mechanical advantage >1

 2) 

   Effort force is located between the fulcrum and the resistance

    Resistance force and effort force are in opposing directions

   so mechanical advantage < 1


If you want further explanation  plz let me know  I can provide you with figure
