Question

How do you solve a Proportion? EX. k/10 = 36/45

Answer 1

Solve k/10 = 36/45?
Multiply both sides by 10..

Answer 2

That doesn't make sense, I mean, I multiplied 36 and 45 by 10 but still, how do I figure out "k" then?

Answer 3

\[\frac{k}{10} = \frac{36}{45}\]Multiply 10 to both sides\[10(\frac{k}{10}) = 10(\frac{36}{45})\]So, you can isolate k on the left, ie you can solve k.

Answer 4

Would the answer be 8? The stupid Sub. at school sucks and she texted the whole time and didn't even teach the lesson.

Answer 5

It is 8.
I'm sorry to hear that :(
