You need a common denominator to add fractions. 12 is the smallest number divisible by 4 and 6. 3/4 = 9/12 2/6 = 4/12 9/12 + 4/12 = 13/12 = 1 1/12

algebra
make everything into twelfths, so you have... 9/12k-2/12 =6/12 take out the 2/12 so... 9/12k=8/12 so now you divide 8/12 by 9/12 = 8/12*12/9 = 96/108 and simplify to 8/9 so k = 8/9
