\[\frac{ a }{ b-a}=\frac{ 5 }{ 9}\]

OpenStudy (anonymous):

a= 5b/14

OpenStudy (anonymous):

b= 14a/5

OpenStudy (anonymous):

I cross multiplied because it's a proportion, 9a = 5(b-a)

OpenStudy (anonymous):

@AriPotta can you help me? I'll give you a medal :)

OpenStudy (aripotta):

after cross-multiplying, you wanna distribute the 5

OpenStudy (anonymous):

9a=5b-5a 14a=5b

OpenStudy (aripotta):

wait are you solving for a or b?

OpenStudy (anonymous):

b

OpenStudy (anonymous):

I have to find the ration from a to b

OpenStudy (anonymous):

@AriPotta

OpenStudy (aripotta):

choices?

OpenStudy (anonymous):

there's no multiple choice for this one :/

OpenStudy (aripotta):

hmm ok

OpenStudy (aripotta):

eh i'm not exactly sure how to do it

OpenStudy (aripotta):

OH

OpenStudy (aripotta):

so a = 5 and if b - a = 9 then b - 5 = 9 and b = 14

OpenStudy (aripotta):

so a/b = 5/14

OpenStudy (aripotta):

@AMYCARTER i'm pretty sure that's the answer :) i was just over-thinking it

OpenStudy (anonymous):

OMG thanks so much!
