Best ResponseYou've already chosen the best response.0I know the first step is to flip the second fraction but I am lost after that

Best ResponseYou've already chosen the best response.0It looks like they want a different method. one denominator is 9 the other is 3x, so the LCD will be 9x.

Best ResponseYou've already chosen the best response.0can you also show me the alternative method that they may want me to use?

Best ResponseYou've already chosen the best response.0lcd is 9x because you need one part of each thing in the denominators. so you need 3x and 9. Since 3 is a factor of both, it's 9x

Best ResponseYou've already chosen the best response.0This is the alternative method where you multiply by 9x/9x on top and bottom.

Best ResponseYou've already chosen the best response.0the other one is where you flip. did you want to go through this both ways?

Best ResponseYou've already chosen the best response.0im sorry i stepped out for a second I want to use the alternative way, please show me

Best ResponseYou've already chosen the best response.0the lcd is 9x, so you have to multiply both fractions by it and then the denominators will cancel dw:1441762561073:dw

Best ResponseYou've already chosen the best response.0wait but, if i flip the other fraction when multiplying, doesnt the lcd change?

Best ResponseYou've already chosen the best response.0ok. the only thing left is to factor the new denominator (3x  18) to 3(x  6) then you can cancel moredw:1441762727663:dw

Best ResponseYou've already chosen the best response.0if you're multiplying you don't use the lcd, you factor and cancel
