Best ResponseYou've already chosen the best response.0a fraction on top of a fraction can be rewritten as say (2/3)/(3/4) then you can flip the second one because to divide you multiply by the reciprocal (2/3)*(4/3) then you multiply across the fractions (2*4)/(3*3).

Best ResponseYou've already chosen the best response.0\[\huge\frac{\frac{30x^2+27x+6}{9x^249}}{\frac{30x+15}{30x70}}\] That is the fraction.

Best ResponseYou've already chosen the best response.0Put a divide sign between both of them, then put them next to each other. You'll know what to do then.

Best ResponseYou've already chosen the best response.0((30x2+27x+6)/(9x2−49))/((30x+15)/(30x−70)) is where we start. then you can flip the bottom half and multiply ((30x2+27x+6)/(9x2−49))*((30x−70)/(30x+15)) then you just multiply though ((30x2+27x+6)*(30x−70))/((9x2−49)*(30x+15))

Best ResponseYou've already chosen the best response.0@cpattison you should use the \\[LaTeX\] by using the \[\\] minus the \ in the middle.

Best ResponseYou've already chosen the best response.0the answer isn't supposed to be like that. it is supposed to be on top of each other though. thats what it says. the answer it: \[\frac{2(5x+2)}{(x7)}\]

Best ResponseYou've already chosen the best response.0You failed to execute the proper steps. That's why you didn't get it right

Best ResponseYou've already chosen the best response.0Did you flip the second fraction?

andriod09

Best ResponseYou've already chosen the best response.0no. i don't know how to solve it like that, you have to factor it out is what the book says, but i don't get it.

Best ResponseYou've already chosen the best response.0If you had \[\frac{3}{6} \div \frac{3}{9}\] you would have no clue what to do?

andriod09

Best ResponseYou've already chosen the best response.0thats simple: \[\frac{3}{6}\div\frac{3}{9}=\frac{1.5}{1}\]

Hero

Best ResponseYou've already chosen the best response.0actually, you have it but you failed to execuate the reciprocal rule

Hero

Best ResponseYou've already chosen the best response.0\[\frac{3}{6}\div\frac{3}{9}=\frac{3}{6} \times \frac{9}{3} = \frac{3}{2}\]

Hero
 2 years ago
Best ResponseYou've already chosen the best response.0But really, you're supposed to do the reciprocal then reduce in this manner: \[\frac{3}{6}\div\frac{3}{9}=\frac{3}{6} \times \frac{9}{3} =\frac{1}{2} \times 3= \frac{3}{2}\]

Hero

Best ResponseYou've already chosen the best response.0Show me the full steps of how you got 1.5 from 3/6 div 3/9 @andriod09

Hero

Best ResponseYou've already chosen the best response.0You must have used a calculator bro, lol

Hero

Best ResponseYou've already chosen the best response.0Because you never divide by fractions to get a decimal. Only a calculator would do that.

Best ResponseYou've already chosen the best response.0\[\frac{3}{6}\div\frac{3}{9}=\frac{3}{6}\times\frac{9}{3}=\frac{1}{2}\times3=\frac{3}{2}\]

Best ResponseYou've already chosen the best response.0How is that the answer though... the answer, from the book, says that the answer is: \[\frac{2(5x+2)}{3x+7}\]

cpattison

Best ResponseYou've already chosen the best response.0I know that bro, but you should have registered that I was trying to show the poor kid something he should have already been familiar with. Ask the majority of students at a school what means over extremes mean and they'll give you a blank stare.

Best ResponseYou've already chosen the best response.0@Hero , but did you notice that I didn't just pop in and say, "extremesovermeans, yo!" and leave? I gave a formula that should be immediately recognized by the more modern phrasing of "keepflipchange." I'll just leave now, because I don't want you to continue derailing the thread just to bark at me.
