Question

After going 3/4 of my journey. I find that I have covered 16 km .How much journey is left?

Answer 1

____________________________________________________________

♦ Elementary Mathematics ♦

→ FRACTIONS : You covered 3/4 th part of your journey

 => If your journey is divided into 4  equal parts, you already covered 3 parts which actually were equal to : 16 km

=> Three-fourth of the Journey is 16 km 

=> Mathematically : [ 3 / 4 ] D = 16
                          => D = ( 64 ) / 3

=> You are left with only 1 part of the journey 
   => Left Part = ( 1 / 4 ) D = [ 1 / 4 ] [ 64 / 3 ]
                                          = [ 16 / 3 ] km

♦ Hence, he actually had to walk : [ 64 / 3 ]km 
 • Journey still left = [ 16 / 3 ] km
