[tex]x-\ all\ students\\\\ \frac{5}{9}x=10\ \ \ \ | divide\ by\ \frac{5}{9}\\\\x=10*\frac{9}{5}=18\\\\ There\ are\ 18\ students\ in\ class.[/tex]
Let us cross multiply.

5/9=10/x

9 x 10= 5x

90=5x

90 ÷ 5= 5x ÷ 5

18=x

So, the answer is 18. I hope this helped you, since I just learned cross multiplication last week.
