Answer :
(1)  →  (B) 4 : 2
(2)  →  (E) 4 : 1
(3)  →  (A) 4 : 4
(4)  →  (D) 2 : 11
(5)  →  (C) 11 : 1
Step-by-step explanation :
As we are given the word MISSISSIPPI.
Now we have to determine the ratio of letters.
In word MISSISSIPPI, there are 1 letter of 'M', 4 letter of 'I', 4 letter of 'S' and 2 letter of 'P'.
Total number of letters = 11
So,
(1) the ratio of S's to P's  = 4 : 2
(2) the ratio of I's to M's  = 4 : 1
(3) the ratio of S's to I's  = 4 : 4
(4) the ratio of P's to letters  = 2 : 11
(5) the ratio of letters to M's  = 11 : 1
