Answer
$\frac{7}{15}$
Work Step by Step
Divide the monomials by cancelling out common factors of the numbers and subtracting the exponents of variables.
$\frac{7x^{30}y^{30}}{15x^{30}y^{30}}$=$\frac{7}{15}$x$^{(30-30)}$y$^{(30-30)}$=$\frac{7}{15}$x$^0$y$^0$=$\frac{7}{15}$
Check the answer.
15x$^{30}$y$^{30}$($\frac{7}{15}$)=$\frac{15(7)}{15}$x$^{30}$y$^{30}$=7x$^{30}$y$^{30}$
