So, I've been doing problems on probablity. Stuff like: 12 over 9 = x over 7, solving for x. But I just got to a question that was this: 2/7 over 3/4 = 5/6 over x I have NO idea how to even begin. Help? D:

$\displaystyle \frac{\frac{2}{7}}{\frac{3}{4}}=\frac{\frac{5}{6}} {x}$ $\displaystyle \frac{2}{7}x=\frac{15}{24}$ ...and I think you can take it from here.
