On the farm, rather than use money, they exchange animals. The exchanges are as follows: 4 bunnies = 3 chickens, 5 chickens = 2 pigs, 3 pigs = 2 donkeys. How many bunnies would you have to trade for a donkey?
+122 To calculate this you'll just need to multiply each of the exchange rates. So bunnies are worth 0.75 chickens (3/4), chickens are worth 0.4 pigs and pigs are worth 0.67 donkeys.
Multiply all of these > 0.75*0.4*0.67=0.2
Since we now know a bunniesis worth 0.2 donkeys we then need (1/0.2=5) 5 bunnies to trade for a donkey.

5 bunnies = 1 donkey
