ok
fisrt we determine sign
negative divided by positive=negative
answer is negative
disregard any signs for now
first convert to from mixed to improper
3 and 1/5=3+1/5=15/5+1/5=16/5
(16/5)/(2/15)
remember the fancy 'invert and multiply'
I won't tell you why because it would take too long, but if you want to know why we invert and multiply, just ask in comments
so, invert an multilply
(a/b)/(c/d)=(ad)/(bc)
(16/5)/(2/15)=(16*15)/(5*2)=(240)/(10)=24
the answer is negative so
-24 is answer
