11+9+5+3.5+1.5=30
Or if it's a trick in the wording then
19+7+3+1=30
(Considering 19 is two odd numbers 1 and 9) so total is five numbers
Another proposal: 5 + 7 + 17 + 1/1 = 30

Is the set of odd numbers is closed under multiplication but is not under addition?
Let + (addition) be a binary operation on the set of odd numbers S. The set S is closed under + if for all a, b ϵ S, we also have a + b ϵ S. Let 3, 5 ϵ the set of odd numbers 3 + 5 = 8 (8 is not an odd number) Since 3 + 5 = 8 is not an element of the set of the odd numbers, the set of the odd numbers is not closed under addition.
