Answer:
A; .31 + 31%
Explanation:
What I did: I put 17,172 over 55,208 as a fraction and to get the percentage I compared the denominator to 100, after this you multiply 17,172 by 100 then divide that by 55,208 to get 31.1316147 which rounds out to 31, once you put that over the 100 that is the percentage ( I may not have explained it the best way possible or the most efficient method, but thats how I got my answer ).
Here is what I did:
……17,172……………?…………….….17,172 x 100 = A
—————— = ————…………..A/55,208 = ? ...55,208………….100…………..…..(? = 31.1316147)
