The sales rate for a community is 6.75 if you purchase an item for $500 how much will you pay in sales tax

33.75 will be how much you pay in sale tax if you multiply 500 times 0.0675

Well, in order to find the answer to this, you would need to divide 6.75 by 500.  Once you do that, then you would take your decimal point and move it to the right two spaces to find your percent.  Now you have your sales tax!  Here is how you would solve this problem:
6.75/500= 0.0135
0.0135=1.35%
1.35% is the sales tax.
