Write as a division of numerator ÷ debominator:

{{{(p^3q^2/m^5n^7)}}}{{{"÷"}}}{{{(p^2q^5/m^2n)}}}

Invert the second and change ÷ to ×

{{{(p^3q^2/m^5n^7)}}}{{{"×"}}}{{{(m^2n/p^2q^5)}}}

Indicate the multiplication of numerators and denominators:

{{{p^3q^2m^2n/m^5n^7p^2q^5}}}

Since there is a p³ on the TOP and a p² on the BOTTOM, we
subtract the exponents 3-2 and get 1, so we write p<sup>1</sup>
or just p on the top because the larger exponent was p³ and it 
was on the TOP, and remove the p² on the BOTTOM:

{{{pq^2m^2n/m^5n^7q^5}}}

Since there is a q&#8309; on the BOTTOM and a q² on the TOP, we
subtract the exponents 5-2 and get 3, so we write q³ on the 
BOTTOM because the larger exponent was q&#8309; and it 
was on the BOTTOM, and remove the q² on the TOP:

{{{pm^2n/m^5n^7q^3}}}

Since there is an m&#8309; on the BOTTOM and a m² on the TOP, we
subtract the exponents 5-2 and get 3, so we write m³ on the 
BOTTOM because the larger exponent was m&#8309; and it 
was on the BOTTOM, and remove the m² on the TOP:

{{{pn/m^3n^7q^3}}}

Since there is an n&#8311; on the BOTTOM and a n<sup>1</sup> on the TOP, we
subtract the exponents 7-1 and get 6, so we write n&#8310; on the 
BOTTOM because the larger exponent was n&#8311; and it 
was on the BOTTOM, and remove the n on the TOP:

{{{p/m^3n^6q^3}}}
