Using proportions, it is found that the correct amount to administer of CC would be of:
A. 0.5.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 500 mg are equivalent to one cc. How many cc are equivalent to 250 mg? Hence the <em>rule of three</em> is given by:
500 mg - 1 cc
250 mg - x cc
Applying cross multiplication:
500x = 250
c = 0.5.
Hence option A is correct.
