I want to know how to find percents of a number.  We have not 
done this during class yet but I am going to take a test for entrance 
exams to other schools.  I want to know before I do that.  They 
always ask you about percents on the ERB's.  

An example is how to find 13 percent of 29.

Hello,

Great Question.

The key to finding percents is to recognize that a percent is just a 
different way to write a decimal.

So in your example, 13% of 29 is the same as asking for 
.13 times 29.

It is as simple as that.

so .13 times 29 is 3.77

so here is another example.

40% of 300

that is just.  .4 times 300, which is  120.

Good luck on your exams.
