Answer 2

You need to use a proportion for this problem. You must set up something like this:
\[\frac{ 6 }{ 15 }=\frac{ 9 }{ x } \]
On top is our centimeters and on bottom is our feet. This says that if 6 corresponds to 15 feet, then 9 corresponds to x ft

Answer 3

To solve for x, you cross-multiply to start with.
