OpenStudy (anonymous):

\[20\div4\]

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

5

OpenStudy (anonymous):

yes, 25 divided by 5?

OpenStudy (anonymous):

5

OpenStudy (anonymous):

7/35 8/40?

OpenStudy (anonymous):

both 5 right?

OpenStudy (anonymous):

0.2

OpenStudy (anonymous):

no

OpenStudy (anonymous):

so the equation is, \[x=5x\]

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

ok? ok, so which do you think should be the answer?

OpenStudy (anonymous):

1.5

OpenStudy (anonymous):

yes or no

OpenStudy (anonymous):

ok, so what is \[\frac{ 4\div4 }{ 4\div20 }??\]

OpenStudy (anonymous):

1/5

OpenStudy (anonymous):

Yes, right, so yes, so you have a 1:5 ratio of Red:White paint. For every 4 cans of red paint, you need 20 cans of white paint. SO you can simplify: For every 1 can of red paint, you'll need 5 cans of white paint.
