Is 5/6 is greater than 10/12
NO. 5/6 is 10/12, since all your doing is multiplying the fraction 5/6 by 2 on both the denominator and the numerator to get 10/12. Since 2 is commonly multiplied, it can be factored out as well, thus leaving 5/6 = 10/12.
no 10/12 is bigger and 5/6 would be smaller as it has less units
