The numerator and denominator of a fraction are in the ratio of 2 to 5. If the numerator and denominator are both decreased by 2, the fraction is now equal to 1/2. If n = the numerator and d = the denominator, which of the following systems of equations could be used to solve the problem? 5n = 2d and n - 2 = 2d - 4
5n = 2d and 2n - 4 = d - 2
2n = 5d and 2n - 4 = d - 2
2n = 5d and n - 2 = 2d - 4
