I think its 1/15 or 2/30
23/30
one third plus one quarter plus one fifth plus one sixth plus six = 6 57/60 1/3 + 1/4 + 1/5 + 1/6 +6: = (20 + 15 + 12 + 10)/60 + 6 = 57/60 + 6 = 6 57/60
(1/5) + (2/6) = (8/15)
11/30
11/15
6/30 + 10/30 = 16/30 or 8/15
1/6 plus 1/5 plus 1/4 plus 1/3 plus 1/2 = 1 9/20 or 1.45
Answer is ten and eleven thirtieths. Found by making the denominators the same at thirty and then adding.
One fifth plus one fifth is two fifths (2/5).
It is: 10
1/6
one third
