If a and b are positive integers such that a/b = 4.37, which of the following must be a divisor of a?	Choose the correct choice from the following.
A) 19 B) 13 C) 12 D) 7 E) 17
1) A and B are positive INTEGERS   2) A/B = 4.37   A = 437   B = 100   437/100=

<output>437/100 = around 4.37</output>
4.37   These values are the smallest values as 437 is neither divisible by 5 or 2, the factors of 100.   The value of B is irrelevant to the question. We're asked for what MUST divide into A....   Since A is a multiple of 437, we have to 'factor-down' 437. This gives us (19)(23). So BOTH of those integers MUST be factors of A. You'll find the match in the answer choices.   19nswer: 19
