Subtract. Simplify by removing a factor of 1 when possible.
(10bf)/(b^2f^2)(bf)/b+f)
Thank you for your help

Europia,
the actual subtraction part is easy: it's two factions being subtracted, which can only be done if they have the SAME denominator. So... the common denominator for the new fraction will be
(b^2  f^2)(b + f)
the numerator is
(10bf)*(b + f)  (b  f)*(b^2  f^2)
the new fraction is
(10bf)*(b + f)  (b  f)*(b^2  f^2)

(b^2  f^2)(b + f)
