The recommended daily intake of potassium ( K ) is 4.725 g . The average raisin contains 3.513 mg K . Fill in the denominators of the fractions, d 1 and d 2 , to complete the conversion factors that can be used to convert between grams and milligrams, given that 1 g is equivalent to 1000 mg . 1 g d 1 mg or 1000 mg d 2 g

Explanation:

It is known that 1 gram contains 1000 milligrams. And, mathematically we can represent it as follows.

              or
