Best ResponseYou've already chosen the best response.01 1/2r  2/3r = 3/2 5/6 = 3/2 6/5 x 5/6r = 6/5 x 3/2 r = 9/5 and simplified that would be r = 1 4/5

Best ResponseYou've already chosen the best response.0@kenialove I don't know. My friend was telling me otherwise :\ I'm confused

Best ResponseYou've already chosen the best response.3First convert the mixed number to an improper fraction \[\Large 1 \frac{1}{2} = 1+\frac{1}{2}\] \[\Large 1 \frac{1}{2} = 1*\color{red}{\frac{2}{2}}+\frac{1}{2}\] \[\Large 1 \frac{1}{2} = \frac{2}{2}+\frac{1}{2}\] \[\Large 1 \frac{1}{2} = \frac{2+1}{2}\] \[\Large 1 \frac{1}{2} = \frac{3}{2}\] Hopefully all this makes sense?

Best ResponseYou've already chosen the best response.0@jim_thompson5910 Could you please solve this expression specifically? It seems easy when I read your work but for some reason the problem above challenges me. :\

Best ResponseYou've already chosen the best response.3do you see how 1 & 1/2 is equal to 3/2 ?

Best ResponseYou've already chosen the best response.0@jim_thompson5910 Yes, but in this equation we're solving for r

Best ResponseYou've already chosen the best response.3So \[\Large 1 \frac{1}{2}r  \frac{2}{3}r = \frac{3}{2}\] turns into \[\Large \frac{3}{2}r  \frac{2}{3}r = \frac{3}{2}\]

Best ResponseYou've already chosen the best response.3The LCD is 6. Multiply both sides by the LCD to clear out the fractions \[\Large \frac{3}{2}r  \frac{2}{3}r = \frac{3}{2}\] \[\Large 6*\left(\frac{3}{2}r  \frac{2}{3}r\right) = 6*\left(\frac{3}{2}\right)\] \[\Large 6*\left(\frac{3}{2}r\right)+6*\left(  \frac{2}{3}r\right) = 6*\left(\frac{3}{2}\right)\] \[\Large 9r4r = 9\] Now solve for r

Best ResponseYou've already chosen the best response.0@jim_thompson5910 THANK YOU! That part with the LCD was what was confusing me so much. You subtract 9r  4r which equals 5r. 5r = 9 r= 9/5

Best ResponseYou've already chosen the best response.3it should be 5r = 9 and not 5r = 9

Best ResponseYou've already chosen the best response.3but you have the right idea: divide both sides by 5 to get r = 9/5
