Which of the following statements must be true?
1) If x/y is a fraction and y has 17 as one of its prime factors then the resulting decimal will be terminating
2) If x/y is a fraction where 2 and 5 are the only two prime factors of y then the resulting decimal will be terminating.
3) If x/y is a fraction such that y=(10^n -1) for n≥1 then the repeating decimals in the result would just be the digits of the numerator.
4) If the interest is accounted annually then for the first compounded interest would be equal to the simple interest.  Choose the correct choice from the following answers
A) 2,3  B) 2,3,4  C) 1,2,3  D) 2,4  E) 1,3
Statement 3: Let's try some examples:   1/9 = 0.11111.....   23/99 = 0.2323232323.....   61/999 = 0.061061061061061.....   Statement 3 is always true.   Statement 4: I think first year is implied by the word "first".   Let's take principal = 100 and interest rate = 20%   Compound interest after 1 year = 100*(1+1/5) - 100= 
<gadget id="calculator">100*(1+1/5) - 100</gadget>
<output>20</output>
20   Simple interest after 1 year= (100*20*1)/100= 
<gadget id="calculator">(100*20*1)/100</gadget>
<output>20</output>
20   Let's take principal= 300 and interest rate = 50%   Compound interest after 1 year = 300*(1+1/2) - 300= 
<gadget id="calculator">300*(1+1/2) - 300</gadget>
<output>150</output>
150   Simple interest after 1 year= (300*50*1)/100= 
<gadget id="calculator">(300*50*1)/100</gadget>
<output>150</output>
150   Statement 4 is always true.   Answer (2,3,4).
