Cows / sheep =6 / 5.......................(1)
Sheep / pigs   =2 / 1.......................(2)
Cows + Sheep + Pigs =189............(3)


Use substitutions to get:
Cows =84,  Sheep =70,   Pigs =35

Ratio    6 : 5 : 2.5           ( 6 + 5 + 2.5 = 13.5 )

189 / 13.5 = 14

Cows     6 * 14 = 84

Sheep    5 * 14 = 70

Pigs        2.5 * 14 = 35  indecision
