To find how many kilometres to next water station or anything else we divided the amount of total km by the denominator of each fraction eg water station every 1/12 of the way.
60/12 =5 water stations every 5km
Grandpy hides behind the bush and you have to guess what fraction of yhe bush he is hiding behind.

You do not add the denomnators togehter you only add the numerators together once they have a common denominator.
I give myself a 29 out of 35.
