Which number, when found in the denominator of any given fraction, gives a terminating decimal?
Choose the correct choice from the following: A) 75 B) 80 C) 85 D) 90 E) 95
75 = 3 * 5 * 5; 80 = 2^4 * 5; 85 = 5 * 17; 90 = 2 * 3^2 * 5; 95 = 5 * 19.   Only Option B has 2 and 5 as factors, hence terminating.   Option 80.
