Basic Math
Okay, Now that the common demoninator is 60, I now multiply. But where do I start? for example, I just leave the 1 alone because its a whole number. So now I multiply the 1/2 to 1 * 30 = 30 and 2 * 30 = 60 Do I do the same for the 1/3 and so on?

I need help adding fractions with different denominators. Here is the problem... 1 - 1/2 + 1/3 - 1/4 + 1/5 - 1/6 I can see that the demoninators increase. Since they are both addition and subtraction, how do I do this problem? Thanks, Walter, New York.
