#9.32#

Explanation:

As a generic approach, a percentage is always a ratio. #x%# simply means #x/100#.

So, if you want to compute the #x%# of a certain number #n#, you only need to multiply #n# and #x/100#, obtaining

#(nx)/100#.

So, you may say that the #20%# of #46.60# is

#\frac{46.60*20}{100}#

However, some percentages are "easy", in the sense that they can be easily computed. For example, #50%# is a half, so instead of multiplying by #50/100#, you can simply divide by #2#.

By the same logic, you have #20/100 =1/5#, which means that the #20%# of something is one fifth of that something. So, it might be easier to compute

#46.60/5=9.32#
