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.
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
