6.25% of 215
The easiest way I found for my students to get this is this two step procedure.
1st cross the OF to get a multiplication sign
6.25% X 215
2nd transform the % into decimal
6.25%=0.0625
Then all you have to do is resolve the equation you get!
0.0625 X 215
=13.44

just multiply 215.00 by .0625 (decimal equivalent of 6.25%) and you will get the answer - use a calculator or manual multiplication
