okay so how these work is you find the least common denominator(a number in which all the denominators share in common after a certain multiplication.) In this case the least common denominator(or LCD for short) is 24 because it is the lowest possible denominator they can share in common by multiplication(8 by 3, 12 by 2, and 6 by 4, all to get 24.) The trick though is that you have to multiply the top and the bottom by the same number so for 5/8 you have to multiply it by 3 over 3 so it comes out as 15/24, for 5/12 its 2/2 so 10/24, and for 1/6 its 4/4 so 4/24. Then you carry out the operations. I like to turn the - sign into a +-(for example 15/24+ -10/24 which gives you 5/24, then you add that to 4/24 for a grand total of 9/24,) but you're not quite done yet. You should make sure the final answer is in its simplest form(in this case you can divide by 3/3 for finally a grand total of 3/8) :) Hope this helps :)
