4/11 divided by 4/9

OpenStudy (phebe):

When you divide a fraction i think you flip it an it turns into a multiplication problem

OpenStudy (phebe):

I'll show you

OpenStudy (abdullahm):

\(\sf\LARGE \frac{a}{b}\div\frac{c}{d} = \frac{a}{b} \times \frac{d}{c}=\frac{a ~\times ~d}{b ~\times~c}\)

OpenStudy (phebe):

|dw:1436386048999:dw| THIS IS THE ORIGINAL PROBLEM

OpenStudy (anonymous):

okay so do i flip both of them or just one half?

OpenStudy (phebe):

my teacher taught us this this thing called skip, flip and then multiply

OpenStudy (abdullahm):

From what I gave you, you can just plug in \(\sf a= 4 \\ b= 11 \\c = 4 \\d=9\)

OpenStudy (anonymous):

so 11/4 divided by 9/4?

OpenStudy (phebe):

Yes

OpenStudy (phebe):

You should also look at this it will help you understand better http://www.purplemath.com/modules/fraction3.htm

OpenStudy (abdullahm):

actually that would get us a wrong answer...

OpenStudy (phebe):

No it would because when you have a problem like she has to flip a multiply is what you should do

OpenStudy (phebe):

and^

OpenStudy (anonymous):

so only one half like in your example @AbdullahM

OpenStudy (anonymous):

i will try both and see what i get..

OpenStudy (anonymous):

okay @AbdullahM i got 44/36

OpenStudy (abdullahm):

that's wrong .-.

OpenStudy (anonymous):

@AbdullahM oh that was the wrong one i got 99/16

OpenStudy (abdullahm):

still wrong...

OpenStudy (anonymous):

i did what you showed me....

OpenStudy (anonymous):

the other thing i would have got 1/3

OpenStudy (abdullahm):

\(\sf\LARGE \frac{a}{b}\div\frac{c}{d} = \frac{a}{b} \times \frac{d}{c}=\frac{a ~\times ~d}{b ~\times~c}\) \(\sf a= 4 \\ b= 11 \\c = 4 \\d=9\)
