Not sure if I am doing this right..... 14/6y+11/9y
is y under the fractions?
yes
then i assume it wants you to add these together. Assume that there is some value which we will call D out there that this is equal to. \[\frac{14}{6y}+\frac{11}{9y} = D\] multiply it all by the lowest denom \[\frac{14(6y)}{6y}+\frac{11(6y)}{9y} = (6y)D\] and simplify \[14+\frac{11(2)}{3} = 6yD\] now multiply it all again by the lowest denom and simplify \[14(3)+\frac{11(2)(3)}{3} = 6y(3)D\] \[14(3)+11(2) = 18yD\] \[42+22 = 18yD\] \[42+22 = 18yD\] i notice here that they are all even so i can divide out a 2 \[42/2+22/2 = 18yD/2\] \[21+11 = 9yD\] \[32 = 9yD\] and finally divide off that 9y \[\frac{32}{9y} = \frac{9yD}{9y}\] \[\frac{32}{9y} = D\] and that should be the brunt of it
of course there is simpler ways to go about it, but they have to deal with remembering certain tricks instead of letting the math work it out
Thank u for the explanation!! I needed that. :)
yer welcome ;)
