Which expression has the greatest value?
Choose the correct choice from the following answers.
A) 1977452 / 1977455  B) 1982466 / 1982469  C) 1982487 / 1982490  D) 1982456 / 1982459  E) 1982465 / 1982468

Rationale: "the difference between each numerator / denominator pair is three . the largest expression ( which in this case will also be the closest to one ) is the expression where ' 3 ' is the smallest fraction of the numerator ( or the denominator ) . the largest numerator is 1982487 , or c , and this will give an expression with a value closest to one . we can also demonstrate that this approach works with some simple logic . taking numerator / denominator pairs that differ by three . . . 1 / 4 = 0.25 2 / 5 = 0.4 3 / 6 = 0.5 . . . 27 / 30 = 0.9 . . . 1982487 / 1982490 = 0.999998486 . . . answer : c"
Answer: C
