Write as a division of numerator ÷ debominator:



Invert the second and change ÷ to ×



Indicate the multiplication of numerators and denominators:



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 p1
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:



Since there is a q⁵ 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 q⁵ and it 
was on the BOTTOM, and remove the q² on the TOP:



Since there is an m⁵ 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 m⁵ and it 
was on the BOTTOM, and remove the m² on the TOP:



Since there is an n⁷ on the BOTTOM and a n1 on the TOP, we
subtract the exponents 7-1 and get 6, so we write n⁶ on the 
BOTTOM because the larger exponent was n⁷ and it 
was on the BOTTOM, and remove the n on the TOP:
