29 adults will need to go
since they go in groups of 15 divide 427 by 15 and you will get 28.47 or 28.466666666666 repeating.
since every group will require one adult there will be 29 adults because the remaining decimal is still a group and will therefore need an adult in addition to the 28 full groups
----------------------------------------------
Find number of groups:
----------------------------------------------
429 ÷ 15 = 28.46

So we will divide the students into 29 groups.
