No, 5/6 is greater.
1) First, you have to get a common denominator, lets use 12
2) To get from 6 to 12 you would multiply times 2
3) Do the same to the numerator(the top number) which is to multiply 5 x 2
4) 5 x 2= 10
5) So, now your fraction has become 10/12
And let me ask you, which is bigger, 10/12 or 2/12
(10/12 is bigger and 2/12 is less)
