Here is another problem that i need on 2/5 divided by 1/6

2/5 divided by 1/6 is the same as 2/5 multiplied by 6
2/5 * 6 = 12/5 or 2.4

2/5 / 1/6 = 
you have to cross multiply so 2x6=12 and 5x1=5 
12 becomes your numerator and 5 your denominator 12/5                    2
thats an improper fraction if you want a mixed fraction that would be 2 ⎻
                                                                                                                5
