One way of attacking this problem would be to cross multiply:

(5/12)k = (5/3)(5/2)
                                    (5/3)(5/2)          25/6       50/12
Solving for k:         k = -------------- = ----------- = ------------ = 10 (answer)
                                        5/12              5/12         5/12
