Question

How do I reduce 10 20/3?

Answer 1

10 20/3 is not a proper way to write a mixed number, the
numerator should be less than the denominator.

so
10 20/3 = 10 + 20/3
= 10 + 6 2/3
= 16 2/3 or just leave it as 50/3

The answer given by the bot is of course just gibberish.

Answer 2

10 20/3 can be reduced to 10 6/3, which is equal to 10 2.
