Option: A is the correct answer.
A. 0.4691
We are asked to convert one unit to another.
We are asked to convert 469.1 milligram into grams.
As we know that milligram is a smaller unit as compared to gram.
Hence, the answer so obtained will be smaller than 469.1
We know:
1 gram = 1000 milligram
Hence, 1 milligram=1/1000=0.001 gram
Hence, 469.1 milligram=0.4691 gram
