Question
The ratio of cows to pigs to chickens on a farm was 15:14:12. Half of the chickens were sold to another farm, and then there were 56 more pigs than chickens. How many animals were on the farm in the beginning? how many chickens were sold?

p/c = 14/12 so p =14c/12 = =7c/6
p - c/2 = 56
======================
7c/6 - 3 c/6 = 56
4 c/6 = 56
c/6 = 14
c = 84 (and 42 were sold)
p = 7 c/6 = 98
cows = 5 c/4 = 105
84+98+105
check my arithmetic !
p - c/2 = 56
