I want to check myself on this one:
a/2 + 1/4 divided by a/3  1/2
you need same denominator so you multiply a/2 by 2 which gives you 2a/4 + 1/4 = 3a/4.
Next part a/3  1/2 so you multiply a/3 by 2 to get 2a/6 then 1/2 you multiply by 3 to get 3/6 so
2a/6  3/6 = 2a3/6. Now 3a/4 divided by 2a3/6 then you use the reciprocal and multiply 3a/4 * 6/3 to get a/2 (after you reduce and cancel out like terms)?

Best ResponseYou've already chosen the best response.1your 1st step has an error:\[\frac{a}{2}+\frac{1}{4}=\frac{2a}{4}+\frac{1}{4}\ne\frac{3a}{4}\]

Best ResponseYou've already chosen the best response.1look at the numerators of that fraction: 2a + 1 = ?

Best ResponseYou've already chosen the best response.1it would just be 2a + 1 / 4

Best ResponseYou've already chosen the best response.1because 2a and 1 are separate

Best ResponseYou've already chosen the best response.1So then it would be 2a + 1/4 divided by 2a  3 / 6

Best ResponseYou've already chosen the best response.1your 2nd step was correct:\[\frac{a}{3}\frac{1}{2}=\frac{2a3}{6}\]

Best ResponseYou've already chosen the best response.1your 3rd step has an error

Best ResponseYou've already chosen the best response.1then 2a + 1 / 4 * 6 / 2a  3

Best ResponseYou've already chosen the best response.1what you want is:\[\frac{2a+1}{4}\div\frac{2a3}{6}=\frac{2a+1}{4}\times\frac{6}{2a3}\]yes  you have it right now :)

Best ResponseYou've already chosen the best response.1yea I saw my error from the first part and realized I made the same mistake and then corrected it

Best ResponseYou've already chosen the best response.1ok  so you know what to do now and understand the process?

Best ResponseYou've already chosen the best response.1you cannot do anything with the 2a + 1 or the 2a  3 because the 2a's are attached to something, so the only thing you can mess with are the 4 and 6, correct?

Best ResponseYou've already chosen the best response.1(2a + 1)*3 / 2*(2a  3) = 6a + 3 / 4a  6 ?

Best ResponseYou've already chosen the best response.1that is correct. although I would leave it in the form:\[\frac{3(2a+1)}{2(2a3)}\]

Best ResponseYou've already chosen the best response.1he he  don't worry too much about it  the main thing here is that you have a good "hunger" for knowledge which means you will go far my friend! :D

Best ResponseYou've already chosen the best response.1thanks for your help! (I haven't "mathed" in about 10 years gosh, that probably gives away my age) I'm a college student again and I'm taking Technical Algebra ... I actually like math now! =)
