The question/problem:
__________________________________________________________
Given:  " 1.6%  sales tax on $720 purchase" ;  how much is the sales tax ? "
__________________________________________________________
To calculate:

" 1.6 %  of $720 is _{what amount }  " ? 

→ 1.6 %   =   (1.6)/100  =  (1.6) ÷ 100  =  0.016   ; 

→ { Note:  To divide "1.6" by "100" ;  take the "1.6" ;  and move the "decimal"
point"  back "2 (two)" spaces .}.  

  →   { We move the decimal point BACKWARD;
              since we are DIVIDING by "100"; 

  →  & we move the decimal point back "2 (TWO)" spaces;
              since there are "2 (two)" zeros in "100" .}.

   →  0.016  *  $ 720 =  ? ; 

   →  The answer is:  " 11.52 dollars " .

             →  write as:  " $ 11.52 " .
