[tex] \frac{15}{8} = \frac{80}{x} [/tex]
At this point in time, you can use a technique called cross-mutiplication, where you say that [tex]15*80=8x[/tex], and [tex]1200=8x[/tex] at this point in time, you can devide each side by 8 and solve

15/8=80/x - You need to cross multiply!!

so... 15x=460
and then... X=42.7
