if I'm not mistaking (please correct if I'm wrong) but I think he would have 16 left.
Step-by-step explanation:
you have to divide one-fifth of 30 which would get you 6, then divide one-third of 24 ( because 30 - 6 is 24) then total both fractions to get 14. then finally subtract 14 from 30 to get 16.
