$\frac{12x^2y}{9yx^9} \div \frac{4x^4y}{x^2y^3}$

OpenStudy (saifoo.khan):

$\frac{12x^2y}{9yx^9} \times \frac{x^2y^3}{4x^4y}$

its the first one

OpenStudy (saifoo.khan):

Yes, then in the second one we flip the second fraction coz we put a multiply.

OpenStudy (saifoo.khan):

$\frac{3x^4y^4}{9y^2x^{13}}$

OpenStudy (saifoo.khan):

$\frac{y^2}{3x^9}$

I'm lost on that one
