If 5a = 6b and ab ≠0, what is the ratio of a/6 to b/5? Choose the correct choice from the following answers.
A) 36 / 25 B) 10 / 12 C) 1 D) 1 / 5 E) 25 / 36

Rationale: "a nice fast approach is the first find a pair of numbers that satisfy the given equation : 5 a = 6 b here ' s one pair : a = 6 and b = 5 what is the ratio of a / 6 to b / 5 ? in other words , what is the value of ( a / 6 ) / ( b / 5 ) ? plug in values to get : ( a / 6 ) / ( b / 5 ) = ( 6 / 6 ) / ( 5 / 5 ) = 1 / 1 = 1 c"
Answer: C
