    it is easy just do 3*4 then add 1 then find a common denominator

    ok so first you have to make 3(1/4) into a as I like to call them, "top heavy fraction" multiply 4*3=12+1=13/4 13/4-6/6

    FInd a common denominator which is twelve because both 6 and 4 go into 12

    13/4=39/12 because: 4*3=12 and 13*3=39

    3 1/4 -6/6 =___ 6/6 is six devided by siz which = 1 so 3 1/4 -1= 2 1/4 or 9/4

    your problem should now look like this: 39/12-12/12=? you can simply subtract across the top now to find your answer your answer should be: 27/12

    why the heck are people using common denominators? 6/6 =1 why not reduce first?

    you can simplify this by asking how many times does 12 go into 27 Answer: 2 times and how much is left over 2(3/12) Your final answer should be : 2(1/4)

    Bethany105 I would look at a problem and try to make it simple. In this case I would look at the fraction this being subtracted 6/6 hey! thats a 1! Now your problem is 3 1/4 - 1 or just plain ole 2 1/4
