you have to multiply them to make the denominators the same, then add the tops. for example: 1/2 + 1/4 multiply 1/2 by 2/2 1/2 becomes 2/4 2/4 + 1/4 = 3/4

another example: 1/3 +2/7 multiply 1/3 by 7/7 to get 7/21 multiply 2/7 by 3/3 to get 6/21 the problem becomes 6/21+7/21, which equals 13/21

if you multiply 2/3 by 2/2, multiply the tops together to get 4, and multiply the bottoms together to get 6. that means that it is 4/6. when you multiply the original fraction with something else, you have to make the second fraction have the numerator and the denominator the same, such as 2/2 and not 1/2. sorry, it is confusing, but do you understand?

well, you have to multiply each fraction by a number to get the denominators the same, so that you can add them together. look at the examples and you will see that I multiply them to get the denominators the same. then i add them together

http://www.aaamath.com/fra66kx2.htm this looks like a good website (never been on it) that you can go on to learn. they probably explain it better than i do!
