A typical multivitamin tablet can contain 2.0 mg of vitamin B2 (riboflavin), and the RDA is 0.0030 g/day. How many such tablets should a person take each day to get the proper amount of this vitamin, assuming that he gets none from any other sources?

First we need to convert these two amounts (0.0030g and 2.0mg) into the same base. Well, it turns out that 1 mg = 0.001g. So, 2mg = 0.002g So how many 0.002g tablets does someone need to take 0.003g of B2? We can divide 0.003g by 0.002g (or really just 3 divided by 2) to find this out. It turns out that the person needs to take 1 and 1/2 tablets a day to get the proper amount of this vitamin. Practically though, the person would probably just take 2 tablets a day.
