what ever number you have in the numerator, match the same amount of numbers in the denominator with 9's. such as: 22/99=.222222, or 34/99=.34343434, or 123/99=.123123123...etc.

Suppose c is a constant such that, for all x, f prime x is equal to c. Use Corollary 7 to prove that there is a constant such that f(x) = cx + d for all x. Let g(x) denote the function c x.

Corollary 7: If f prime x = g prime x for all x in an interval (a,b), then f - g is constant on (a,b); that is, f(x) = g(x) + c where c is constant.
