The given numbers are all odd. The sum of 5 odd numbers must be odd. 50 is not odd so there is no solution.
There are no four odd numbers that will add up to nineteen.
3, 7 and 9. 4 odd digits that add up to 19 would be 9, 9, 0.5, 0.5
It is not possible to add together 5 odd numbers to make an even number.
that question cant be answered unless it was 3 odd-digits or 4 odd-digits with 1 even digit i think.

It is even. Both numbers end with odd digits and two odd digits always add to an even number. You can see that is the case in this instance.377 + 87 = 464

1.5 and 1.5 easy peasy
You cannot add 4 odd NUMBERS to make an odd number, so you have to think constructively...eg 1 + 3 + 15 = 19. There are other similar solutions...
This is impossible. 21 is an odd number and all these digits are odd. Whenever you add 6 odd numbers together, the answer is always even!
The answer is infinite. There is no collection of nines so large that you can't add another nine to it.
