A person is told to take 1.25 mg of vitamin d daily. how many 0.125-mg tablets should this person take?
vovikov84 [41]
This is a simple calculation involving drug doses.

The solution is as follows:

(0.125 mg/tablet)(n) = 1.25 mg
n = (1.25 mg)/(0.125 mg/tablet)
n = 10 tablets

So a person needs to take ten 0.125 mg tablets of vitamin D to have that 1.25 mg dose.
