Question

is writing 4\3 as 1 1\3 the same as reducing the fraction

Answer 1

not quite. They are equal but 4/3 is what's more considered to be the reduced form. 1 and (1/3) is called a mixed form (I think?) and it's not so commonly used.

Answer 2

Yea Pyeh is right, Its mixed form, not as common. The reduced form is 4/3 which is correct and proper way to write it.

Answer 3

..yes.
