First set up the equation (6 – 2) + (1/8-3/4). Then, find the common denominator of 1/8 and 3/4 which would be 8. Next, find how many times does 4 have to be multiplied to get 8 or the least common multiple which is two. Then, multiply it, after that subtract 6-2=4 then 1/8 - 6/8, you can't subtract 1-6 but you have the 4. 1-6= -5 .Next, the equation now should be 4+-5/8 then you do the equation 4+-5/8=3.375 or 3 3/8.
