4/3x + 4 2/3 equivalent to

I believe this question should be a multiple choice question as there are numerous solutions.

Some of these solutions are:

4/3x + 4 2/3 = 4/3x + 8/3

4/3x + 4 2/3 = 8/6x + 4 4/6

4/3x + 4 2/3 = 12/9x + 4 2/3

This can be explained as:

For 8/6x + 4 4/6, divide the numerator by 2 and the denominator by 2 in each of the terms, the output will be the original expression.

For 12/9x + 4 2/3, divide the numerator by 3 and the denominator by 3 in the first term (12/9x), the result will be the original expression.
