it is in the daily average for the high and low average i just want to reduce so i can align the table

this is the outcome i get

     Day        Highs        Lows        
    ------       -----         ----       
    Monday         68           55    
   Tuesday         70           56    
   Wensday         52           40    
  Thursady         70           62    
    Friday         55           42    
  Saturday         51           40    
    Sunday         52           36    
Daily Average    59.714285714285715   47.285714285714285           
Highest Day      Thursady     Thursady    
Lowest Day       Saturday      Sunday   

i wanna reduce the decimal place in the daily average..
