#140%# of #250# is #350#.

Explanation:

#140%# of what number is #350# is equivalent to

#140/100# of what number is #350#.

Let the number be #x#, then

#140/100×x=350# or

#x=350×100/140# or dividing by #20#

#x=350×(5cancel100)/(7cancel140# and now dividing by #7#

#x=(50cancel7)×5/(cancel7)#

or #x=50×5=250# i.e.

#140%# of #250# is #350#.
