In order to answer this: 81x = 36 ;; x = 36/81. You can simplify this by a factor of 9 and you get 4/9.
2/81
You cannot simplify 31 over 36 because 31 is prime.
Yes.
you do
81/200 is in its simplest terms
Yes
36/8 = 9/2
one over two
36/81 = 4/9 = 8/18
The greatest common factor between 36 and 81 is 9. 36/9 = 4 and 81/9 = 9.36/81 = 4/9.
