Q

to convert 1:100,000, 1:500,000 to mcg/mL what do you do?

A

divide denominator by 1,000,000
ex 1:100,000 = 10mcg/ml (also if you keep the same and do it divided to 1,000 it will give u g/mL then you can convert that into mcg/mL)
ex 1:100,000 = 0.01g/mL then move decimal for mcg 10mcg/mL either way works
