Mark had 4 members in his family each of the person get 1/6 what is the fraction of the tomato use fraction strips

If each person got 1/6 then there is still 2/6 left over, =1/3. In fraction strips, we would do

                  1

  1/3         1/3        1/3                                                                 1/3

1/6 1/6   1/6 1/6  1/6 1/6 for the overall tomato and then  1/6 1/6  for the remaining piece of the tomato.

Hope this helps, if you need any more help just comment :)
