Final answer:
To convert 1.1mg to grams, divide it by 1000 since 1 gram is equal to 1000 milligrams.
Step-by-step explanation:
To convert 1.1mg to grams, we can use the known fact that 1 gram is equal to 1000 milligrams. So, we can set up a proportion:
1g = 1000mg
x g = 1.1mg
Cross-multiplying, we get:
x = (1.1mg * 1g) / 1000mg
x = 0.0011g
Therefore, 1.1mg is equal to 0.0011 grams.
