David takes 300 milligrams of medicine every day. Find this rate in grams per day
1 milligram = 0.001 grams
300 * 0.001 = _____ gram
0.3 grams
To find the rate in grams per day, we need to convert milligrams to grams. Remember that 1 gram is equal to 1000 milligrams.
To convert 300 milligrams to grams, divide it by 1000:
300 milligrams / 1000 = 0.3 grams
So, David takes the medicine at a rate of 0.3 grams per day.
