You can do it that way, or you can normalize the odds to 1, and see if the three horses you like have less than 80% of the total. For example, let's say there's one with .10 of the total and another with .20 and another with .30. That's .60 of the total which is less than .80, so (roughly) you would bet 1/6 of your bet on the .10 horse; 2/6 on the .20 horse and 3/6 on the .30 horse to complete the dutch.
(As an aside, monte carlo has nothing to do with it)
