What is 5 minus one third?

Answer 1

The question is ambiguous. There are two plain readings:

In the first, 5 - 1/3 = 4 2/3 or four and two thirds. Expressed as a decimal, this is equal to 4.6 recurring (that is, 4.6666...).

In the second, 5 - one-third OF 5 is 5 - 5/3 is 10/3, or 3 1/3, or three and one-third.
