Explications :

Mettre le singulier ou le pluriel après un pourcentage ?

==> Si % ( percent) est suivi de "of" + un nom au pluriel  alors le verbe au pluriel

ex : 55% of the children go to school

==> Si % est suivi de "of" + un nom singulier alors le verbe sera au singulier.

ex: 55% of the win is left in the bottle.
