Divide: 15m^4n^3-35mn^2/5mn

To divide (15m^4n^3 - 35mn^2) by 5mn, you need to simplify the expression by dividing each term by 5mn.

Divide the first term (15m^4n^3) by 5mn:
(15m^4n^3) / (5mn) = 3m^3n^2

Divide the second term (-35mn^2) by 5mn:
(-35mn^2) / (5mn) = -7n

Therefore, the simplified expression is:
3m^3n^2 - 7n
