assuming that dot means multiply

remember

((a)/(b))((c)/(d))=(ac)/(bd)

so
remember that it is helpful to factor them to simplify


((x-5)/(3x+12))((2x+8)/(2x-10))=

((x-5)(2x+8))/((3x+12)(2x-10))=

((x-5)(2)(x+4))/((3)(x+4)(2)(x-5))=

(((x-5)(2)(x+4))/((x-5)(2)(x+4)))((1)/(3))=

(1)((1)/(3)=

(1)/(3)
