Multiply the denominator by the whole number( 12 and 5) then add the numerator (so now it's -67/12). Do the same thing with 10 3/4 ( so now it's 43/4). Multiply 43/4 by 3 so you have a common denominator of 12. So now you have -67/12 + 129/12. Just do the math and then simplify. And by simplify I mean find a number that you can divide both the top and bottom of the fraction by to get the numbers as small as possible.

Find LCD (Least Common Denominator) 12 in this case. Convert 3/4 =9/12
10 9/12 - 5 7/12 = 5 2/12 or 5 1/6

Find LCD (Least Common Denominator) 12 in this case. Convert the fractions
-(5 x 12 + 7) / 12 + (10 x 4 + 3) / 4 OR -67/12 + 43/4
or 129/12 - 67/12 = 62/12 or 5 2/12 again 5 1/6
