Answer:
-1/16
Explanation
6 7/8 - 6 15/16
To make the problem easier, we are gonna have to change the denominator into 16
8*2=16 after we times 8 with 2 we now have to do the same 7
So this would show 7*2=14
Now it would be 6 14/16 - 6 15/16
All we have to do now is minus 14 with 15 which equals -1.
Now for the whole numbers, you can just minus the 6’s with eachother 6-6=0. Taking the denominator, we now have -1/16.
Hope this is the answer you are looking for.
