Round each fraction to 0, 1/2, or 1/5, 4/7, 11/12, and 2/15

Well the best thing to do would be to say what each of these fraction is stating.  1/5 means 1 out of 5.  That's closes to 0.  4/7 is saying 4 out of 7.  1/2 of 7 is 3.5 so that is closest to 1/2.  11/12 is saying 11 out of 12.  That's almost a whole.  So that's closest to 1. and 2/15 is saying that only 2 of 15.  So that's closest to 0 as well.

1/5=0
4/7= 1/2
11/12 =1
2/15=0
