Question

How do you divide `\frac { \frac { 20x ^ { 3} y } { 7m n ^ { 2} } } { \frac { 5x ^ { 5} y ^ { 3} } { 14n ^ { 5} } }`?

Answer 1

`(8n^3)/(x^2y^2m)`

Explanation:

You can write the above as:
`(20x^3y)/(7mn^2)*(14n^5)/(5x^5y^3)`

And that will multiply together as:
`(20x^3y)/(7mn^2)*(14n^5)/(5x^5y^3)=(280x^3yn^5)/(35x^5y^3mn^2)=(8n^3)/(x^2y^2m)`
