Post subject:  If a is an integer greater than 4 but less than 21 and b is an integer 
If a is an integer greater than 4 but less than 21 and b is an integer greater than 14 but less than 31, what is the range of a/b? A. 2/3 B. 1/2 C. 5/6 D. 1 E. 7/6

The way to approach this problem is 4<a<21 and 14<b<31 Minimum possible value of a is 5 and maximum is 20 Minimum possible value of b is 15 and maximum is 30 Range = max a/min b  min a/max b (Highest  lowest) 20/15  5/30 = 7/6 Hence E

Range of a/b = max(a/b)  min(a/b) to get max(a/b) => max(a)/min(b) = 20/15 to get min(a/b) => min(a)/max(b) = 5/30 Range = 20/15  5/30 = 7/6

hi i think the question should be little more elaborate.....range of the set a/b is something that cannot be assumed from the question

Range will be maximum minimum = maximum of a/ minimum of b  minimum of a/ maximum of b = 20/15  5/30 = 35/30 = 7/6. Option E

A. 2/3 B. 1/2 C. 5/6 D. 1 E. 7/6 A positive fraction is maximized when the numerator is as large as possible and the denominator is as small as possible. Thus, the maximum value of a/b is 20/15 = 4/3. Similarly, a positive fraction is minimized when the numerator is as small as possible and the denominator is as large as possible; thus, the minimum value of a/b is 5/30 = 1/6. Therefore, the range of values of a/b is 4/3  1/6 = 8/6  1/6 = 7/6. Answer: E
