Answer: 3.88 to 219
Step-by-step explanation: ok so if the data is O+ donors to B+ donors and you have to write the comparison in three different ways then you look on the chart to see that O+ is 97 & B+ is 25 then it would be 97 to 25. 97 t0 25 & 25 to 97 So I’m thinking next you have to divid 97 by 25 to get 3.88 to 219 .
I might be wrong and if I am i’m sorry.
