Which fraction should be added to:
1/(2 Ã— 3) + 1/(3 Ã— 4) + 1/(4 Ã— 5) + ....... + 1/(29 Ã— 30)
so that the result is equal to 1?	Select the correct option:
A) 4/15 B) 7/15 C) 8/15 D) 11/30 E) 13/30
The given expression   = 1/(2 Ã— 3) + 1/(3 Ã— 4) + 1/(4 Ã— 5) + ...... + 1/(29 Ã— 30)   = (1/2 - 1/3) + (1/3 - 1/4) + (1/4 - 1/5) + .......... + (1/29 - 1/30)   = 1/2 - 1/30 = 14/30   Thus, the fraction we should add = 1 - 14/30 = 16/30 = 8/15   The answer is 8/15.
