    Question Adding these Fractions?



    Can anyone explain to me how that turned into 2/2?

    I understand why the denominator turned into 2. But how did the numerator turn into 2?

    \frac{\frac{1}{3T}+3}{2T-2} would become \frac{\frac {3}{3T}}{2T-2} But past that... \frac{T}{2T-2} I believe. \frac{1}{T-2} Possibly. :s Been a while. Algebra 1?

    Go to the LaTeX help section, it teaches you how to write the fractions and stuff like me, quite easy and makes things more understandable.

    But from what I understood.

    (1/2) * (3) = (3/2)

    And

    (1/2) + (3) = (1/2) + (6/2) = (7/2)

    So how can the (3) just combine with the (1/3t) when there is a + sign separating them?????

    \frac{\frac{1}{6}+3}{2} Then \frac{\frac{19}{6}}{2} ???

    *Can anyone please at least tell me if I understood it wrong. I've been reading my book and doing the problems and it all seems to follow that rule. I don't understand why this problem is different.*

    Unhappy

    Can you explain to me why (1/6) + (3/1) = 2?

    Shouldn't it be (1/6) * (3/1) = 2?

    No, no one can because it's not true! If T= 2 then the numerator is \frac{1}{6}+ 3= \frac{1}{6}+ \frac{18}{6}= \frac{19}{6} and the entire fraction is equal to \frac{19}{12}, not "1".

    I understand why the denominator turned into 2. But how did the numerator turn into 2?
    Oh and (1/6)*(3/1) is 1/2 not 2.
