1  (3/4)x > 0 is equivalent to x < 4/3.

In any case, the statement "X is a whole number. if three quarters of x is subtracted from 1,the result is always greater than 0" is not always true. But there was no question asked in the original post. Chriskwajaffa, was the problem to determine values of x such that the statement is true? If so, is the same as . Multiply on both sides by the positive number 4/3 (do you see why the fact that it is positive is important?) to get . So the statement is true for all x less than 4/3.
