Which of the following fractions can be written as the difference of reciprocals of two consecutive integers Choose the correct choice from the following choices:  A) 1/24  B) 7/30  C) 1/30  D) 13/56  E) 1/73
Difference of reciprocals means 1 has to be in the numerator;   So option BD can be ignored   For option A, BE, we require to search two consecutive numbers whose product is the denominator   24 = 4 * 6 ......... Ignore   30 = 5 * 6 ........ Answer   73 = 7 * 9 ................ Ignore   Answer = 1/30
