Set A = {x : x = n/(n+1), where n is a natural number and 1 ≤ n ≤ 6} in roster form is:
A{1/1, 2/2, 3/3, 4/4, 5/5, 6/6}
B{1/2, 1/3, 1/4, 1/5, 1/6, 1/7}
C{2/1, 3/2, 4/3, 5/4, 6/5, 7/6}
D{1/2, 2/3, 3/4, 4/5, 5/6, 6/7}
Answer & Solution
Correct answer: D. {1/2, 2/3, 3/4, 4/5, 5/6, 6/7}
For n = 1 to 6, n/(n+1) gives 1/2, 2/3, 3/4, 4/5, 5/6, 6/7.
