S is the set of all fractions defined by the formula n/(n + 1), where n is a positive integer less than 20. What is the product C of all the fractions that are in S?	Choose the correct choice
A) 1) 1/20
B) 2) 1/21
C) 3) 1/2
D) 4) 19/40
E) 5) 19/20
1/2 * 2/3 * 3/4 * ... 19/20   = 1/20   1) 1/20nswer - 1) 1/20
