Best ResponseYou've already chosen the best response.0are you solving for \[R\] \[R_1\] or \[R_2\]?

Best ResponseYou've already chosen the best response.0subtract \[\frac{1}{R_2}\] from both sides, take the reciprocal

Best ResponseYou've already chosen the best response.0\[\frac{1}{R}\frac{1}{R_2}=\frac{1}{R_1}\]

Best ResponseYou've already chosen the best response.0\[{1 \over R}  {1 \over R2} = {1 \over R1} ? \]

anonymous

Best ResponseYou've already chosen the best response.0\[\frac{R_2R}{RR_2}=\frac{1}{R_1}\]

Best ResponseYou've already chosen the best response.0haha. same thing! this is good!

Best ResponseYou've already chosen the best response.0now flip everything to get \[\frac{RR_2}{R_2R}=R_1\]

Best ResponseYou've already chosen the best response.0where did you come up with the last one?

anonymous

Best ResponseYou've already chosen the best response.0the one before the last... not flipping but the previous one

anonymous

Best ResponseYou've already chosen the best response.0oh i had 1/R and wanted R. just flip it

anonymous

Best ResponseYou've already chosen the best response.0oh previous one. ok hold on

Best ResponseYou've already chosen the best response.0\[\frac{1}{a}\frac{1}{b}=\frac{b}{ab}\frac{a}{ab}\] yes? common denominator is ab and i have to build up the fractions

anonymous

Best ResponseYou've already chosen the best response.0then you subtract to get \[\frac{ba}{ab}\]

Best ResponseYou've already chosen the best response.0no. give me a second. i'm going to write it...

anonymous

Best ResponseYou've already chosen the best response.0ok if not clear let me know. think of \[\frac{1}{5}\frac{1}{3}\]

anonymous

Best ResponseYou've already chosen the best response.0this: \[\frac{1}{a}\frac{1}{b}=\frac{b}{ab}\frac{a}{ab} \] is important for me to remember. i am taking note of it. i think it's just that i need to understand this before being able to do these kind of problems. does that sound right from what you are seeing with me?

anonymous

Best ResponseYou've already chosen the best response.0yes, but don't get married to that formula. to add and subtract fraction it is always \[\frac{a}{bb}\pm\frac{c}{d}=\frac{ad\pm bc}{bd}\]

Best ResponseYou've already chosen the best response.0thanks for confusing me more :p

anonymous

Best ResponseYou've already chosen the best response.0just in this case the numerators happened to be 1!

anonymous

Best ResponseYou've already chosen the best response.0that should really not confuse you much. how do you add \[\frac{2}{3}+\frac{5}{7}\]? it is just \[\frac{2\times 7 + 3\times 5}{3\times 7}\]

anonymous

Best ResponseYou've already chosen the best response.0i would rather find the common denominator for the fraction with numbers lol

anonymous

Best ResponseYou've already chosen the best response.0but you are showing me a more advanced way. i believe i must learn this way to be succesful

anonymous

Best ResponseYou've already chosen the best response.0in your case it was \[\frac{1}{R}\frac{1}{R_2}=\frac{1\times R_21\times R}{R\times R_2}\]

anonymous

Best ResponseYou've already chosen the best response.0so the 1's were eliminated.... then we are left with variables

anonymous

Best ResponseYou've already chosen the best response.0wtf. that's the easiest way to add fractions that i have seen.

anonymous

Best ResponseYou've already chosen the best response.0thank you again! so the: \[\frac{a}{bb}\pm\frac{c}{d}=\frac{ad\pm bc}{bd} \] applies to all fractions?
