a gestation period for a donkey is 12 months
Once every 11 to 12 months, accounting for the period of rest a cow gets after being bred (which will last from 2 to 3 months), and the gestation period for that cow after she has conceived.
3 months/1 year = 3 months/12 months = 3/12 which can be simplified to 1/4.
3 years = 12*3 months = 36 months. 1 trimester = 3 months so 36 months = 36/3 = 12 trimesters.
The exact fraction actually depends on which 3 months you are considering - but as a simple answer, since there are 12 months, 3 months would be 3/12 = 1/4 of a year.
