18 x (-5/6)

OpenStudy (anonymous):

it that "X" a variable or a multiplication sign?

OpenStudy (anonymous):

18(-5/6)

OpenStudy (anonymous):

-10

OpenStudy (anonymous):

howd you get that?

OpenStudy (anonymous):

okay 18(-5/6) is the same as -60/6 which is equal to -10

OpenStudy (anonymous):

but 18/1 x 5/6 reduces down to 3/1 x 5/1 right?

OpenStudy (anonymous):

What... oh wow... nvm...

OpenStudy (anonymous):

yeah, and you used cross cancellation, which is a really good method, that not a lot of people get. :) The answer would then be -15 :)

OpenStudy (anonymous):

thanks!

OpenStudy (anonymous):

correct at -15
