Answer:
(a) Ratio of A to B = 17566 : 5827
(b) Ratio of B to A = 5827 : 17566
(c) A is 301.46% percent of B.
Step-by-step explanation:
We are given A = 52,698 number of deaths due to a deadly disease in the United States in 2005  and  B = 17,481 number of deaths due to the same disease in the United States in 2009.
(a) Ratio of A to B = [tex]\frac{A}{B}[/tex] = [tex]\frac{52,698}{17,481}[/tex] = 17566 : 5827
(b) Ratio of B to A = [tex]\frac{B}{A}[/tex] = [tex]\frac{17,481}{52,698}[/tex] = 5827 : 17566
(c) Let A is x% of B so the equation formed will be;
  A = x% of B
   52,698 = x% of 17481
 Therefore x = [tex]\frac{52,698}{17,481}*100[/tex] = 301.46%
Hence, A is 301.46% of B.
