In simplest terms, two and two-thirds divided by one and one-sixth = 16/7 or 22/7
Two divided by one fifth is the same as two times five. The answer is ten (10)
In lowest terms, two and one half divided by two and one sixth = 15/13 or 12/13
Six and one third divided by two and one half is 28/15
Two halves is one. And anything divided by one is itself. So the answer would be two twelfths - except that it simplifies to one sixth.
One and one half divided by two thirds = 9/4, or 2 and 1/4
