OpenStudy (keythemusician):
Is this a fraction -> -4/9
OpenStudy (kimberly_pr):
Yes :)
OpenStudy (keythemusician):
Alright, so we need to divide \[-\frac{ 4 }{ 6 }\] from both sides
OpenStudy (keythemusician):
I think

Maybe not
OpenStudy (keythemusician):
Oh, we need to simplify both sides of the equation then isolate w
OpenStudy (keythemusician):
So what can -4/6 simplify to?
OpenStudy (kimberly_pr):
Wouldn't we divide both sides by -4/9 to isolate it form the w?
OpenStudy (keythemusician):
Well, yes but it will probably be easier if we simplify

Why are you simplifying -4/6 when it is -4/9
OpenStudy (keythemusician):
I screwed it up sorry
OpenStudy (helpppp):
oh. It's fine. I just thought you had moved the 4 or something
OpenStudy (keythemusician):
I think I just mentally flipped the 9

And remember when you multiply or divide by a negative you flip the inequality sign
OpenStudy (kimberly_pr):
Now do we multiply -6/1 by 9 to make them have equal bases or?
OpenStudy (kimberly_pr):
Or do we just divide as it is?
OpenStudy (helpppp):
Do -6*9 and 1*-4 to give you your new fraction
OpenStudy (keythemusician):
Yeah cross multiply

And then simplify your answer and bam
OpenStudy (kimberly_pr):
SO -4/-54? And then simplify to -2/-27? @helpppp
And sorry I had to go do something
