Hello there, and thank you for asking your question here on brainly.
Short answer: -7/12
Why?
So, here are the steps on how to solve this. It takes a bit of work. (First step: 6/4 can be simplified down to 3/2, so do that.) - (Second step: Find the least common denominator. The least common denominator is 12. Convert 3/2 to a 12 denominator by multiplying both sides by 6. {3 * 6} / {2 * 6} ==> 18/12) - (Third step: Subtract the numerators. {11}/12 - {18}/12 ==> -7/12
