How do you add the top number of the unlike fraction?
You find the least common denominator and then you see how many times the denominator of the actual fraction goes into it, then you multiply that by how many times it goes into the least common denominator, then you just do it for the other fraction as well, example:6/9+3/7= The least common denominator is 56 bcuz 9 and 7 dont go into eachother, then you find how many times 9 goes into 56: which is 7 so you multiply it by 6 and you have 56/56= 1 whole, so thats the first fraction and you do the same thing to the nextYou can go to YouTube to find GREAT videos!Josh W.
