((a+b)/c)/2
In the expression above, a, b, and c are different numbers and each is one of the numbers 2, 3, or 5. What is the least possible value of the expression?	Pick one.
A) 2 / 10  B) 5 / 10  C) 10 / 5  D) 7 / 6  E) 6 / 7

Rationale: ( ( a + b ) / c ) / 2 = ( a + b ) / 2 c the expression will have the least value when numerator ( a + b ) is the smallest . = ( 2 + 3 ) / 2 * 5 = 5 / 10 answer b
Answer: B
