Spending the salary

[Crack1]

Il a déjà dépensé les deux tiers de son salaire.

He has already spent a two third of his salary.

Have I translated into correct English?

[stu harris]

Not quite. It's

He has already spent two thirds of his salary.

Depending on the context, the following might be better:

He has already spent two thirds of his wages.

The difference is that salary always refers to ANNUAL pay. Wages are usually computed weekly or monthly. Although either statement might be correct, most people calculate their budgets weekly or monthly.
