If Rick Colors 1/2 Of A Poster And Jenny Colored 1/3 Of The Poster How Much Is Left To Color?

Rick colors --- 1/2 poster
Jenny colors ---1/3 poster

The total poster that they have colored:

1 + 1
2    3

= 1x3 + 1x2
    2x3    3x2  
= 3 + 2
      6
= 5
   6

Therefore, Rick and Jenny have colored a total of 5/6ths of the poster. To find out how much of the poster is still left, we will subtract this value from 1:

1 - 5
     6
= 1x6 - 5
       6
= 6 - 5
      6
= 1
   6
So, 1/6th of the poster is left to color.
