Solve the inequality for w: -4/9 w > -6 Simplify as much as possible

OpenStudy (kimberly_pr):

@triciaal @keythemusician @AloneS @helpppp

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

OpenStudy (keythemusician):

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

OpenStudy (helpppp):

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

OpenStudy (keythemusician):

OpenStudy (keythemusician):

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

OpenStudy (helpppp):

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
