    so we could multiply the top fraction to get 12x

    Good. Now get a common denominator of 24 in the numerator and the denominator.

    Multiply the numerator and the denominator of each individual fraction by the appropriate number.

    would it be 6x/25 + 8y/24 divided by 8x/24 - 3y/24

    After the fraction x plus 1 all over 2 minus the fraction x plus 2 all over 3 x have been combined using the least common denominator of 6x, what is the numerator?

    see how I am not completely multiplying the denominator to obtain the LCD when variables are involved? it is a trick so you won't have to do extra work since you will immediately see that when you divide, it cancels out the other.
