Answer
$\frac{9}{7}$
Work Step by Step
Divide the monomials by cancelling out common factors of the numbers and subtracting the exponents of variables.
$\frac{9x^{20}y^{20}}{7x^{20}y^{20}}$=$\frac{9}{7}$x$^{(20-20)}$y$^{(20-20)}$=$\frac{9}{7}$x$^0$y$^0$=$\frac{9}{7}$
Check the answer.
7x$^{20}$y$^{20}$($\frac{9}{7}$)=$\frac{7(9)}{7}$x$^{20}$y$^{20}$=9x$^{20}$y$^{20}$
