Have you ever heard to use parentheses?

(5V - 10)/21 // (V - 2)/35

(5V - 10)/21 * 35/(V - 2)

35(5V - 10)/21(V - 2)

(175V - 350)/(21V - 42)
------these are not factors, so I see no further simplification

((5v-10)/21)/((v-2)/35)
  = (5v-10)/21*35/(v-2)    (invert the denominator and multiply)
  = 5(v-2)/(v-2)*35/21    (factor 5v-10 to 5(v-2))
  = 5*(5*7)/(3*7)    (factor 7 from 35 and 21)
  = 25/3
