What is 3/4 of 16? can you show an example?

3/4 of 16 simply mean what is 3/4 times 16. OF means MULTIPLICATION, there for we know that we have to multiply. 

  3       6        18
x  =    now since we have and improper fraction, we divide. 2  4
  4       1          4                                                                                            
                                                                                                                        4 is now the answer, but we have to simplify.         2  1
                                                                             
                                                                                1  is the final answer.

(hope this helps)
