If a is an integer greater than 6 but less than 17 and b is an integer greater than 3 but less than 29, what is the range of a/b? Choose the correct option:
A) 15 / 4 B) 13 / 2 C) 9 / 7 D) 1 / 5 E) 7 / 6

Rationale: "the way to approach this problem is 6 < a < 17 and 3 < b < 29 minimum possible value of a is 7 and maximum is 16 minimum possible value of b is 4 and maximum is 28 range = max a / min b - min a / max b ( highest - lowest ) 16 / 4 - 7 / 28 = 15 / 4 hence a"
Answer: A
