If 7a = 8b and ab ≠0, what is the ratio of a/8 to b/7? Choose the correct option
A) 16 / 14	B) 8 / 7	C) 1	D) 7 / 8	E) 64 / 49

Rationale: "a nice fast approach is the first find a pair of numbers that satisfy the given equation : 7 a = 8 b here ' s one pair : a = 8 and b = 7 what is the ratio of a / 8 to b / 7 ? in other words , what is the value of ( a / 8 ) / ( b / 7 ) ? plug in values to get : ( a / 8 ) / ( b / 7 ) = ( 8 / 8 ) / ( 7 / 7 ) = 1 / 1 = 1 c"
Answer: C
