Final answer:
The correct answer is option b:The difference of 5/6 - 3/4 is a whole number.
Step-by-step explanation:
The statement that is true about 5/6 - 3/4 is that the difference is a whole number (Option B).
To find the difference between two fractions, we need to have a common denominator. In this case, the least common denominator is 12. We can multiply 5/6 by 2/2 to get 10/12, and multiply 3/4 by 3/3 to get 9/12.
Subtracting 9/12 from 10/12 gives us 1/12, which is a whole number. Therefore, Option B is the correct statement.
