Question

Help please! :)

What value of x solves the following proportion?
9/6=x/8

6(3/4) 11
10(1/2) 12

Answer 1

\[\frac{ 9 }{ 6 }=\frac{ x }{ 8 }\]
As the problem says, it's a proportion, so let's multiply in cross:
\[9(8)=x(6)\]
Just to convert in a simple ecuation, now let's multiply:
\[72=6x\]
And solving for x:
\[x=\frac{ 72 }{ 6 }\rightarrow x=12\]
And done :)
