Multiplication
#a/b cdot c/d={a cdot c}/{b cdot d}# Division
#a/b divide c/d=a/b cdot d/c={a cdot d}/{b cdot c}#
I hope that this was helpful.

Remember that dividing by a fraction is equivalent to multiplying by the reciprocal of the fraction, that is,
#a/b divide c/d = a/b cdot d/c={a cdot d}/{b cdot c}#
I hope that this was helpful.

I would just turn it into multiplications.
#a/b divide c/d divide e/{f} = a/b times d/c times f/e={a cdot d cdot f}/{b cdot c cdot e}#
I hope that this was helpful.

Division of a rational expression are similar to fractions.For dividing rational expressions, you will use the same method as you used for dividing numerical fractions: when dividing by a fraction, you flip-n-multiply. For instance:
#[ (x^2 + 2x - 15) / (x^2 - 4x - 45) ] ÷ [ (x^2 + x - 12) / (x^2 - 5x - 36) ]# here as you see i have factored the different expressions and cancelled the common expression finally it gets reduced to nothing
Hope this helped you
