The correct answer is: " 3,000 mg " ;
that is; "Three-thousand milligrams."
____
Explanation:
____
Note: The following is an "exact figure" conversion:
1,000 mg = 1 g ; ↔ 1 g = 1,000 mg ;
(i.e. "One-thousand" milligrams = 1 gram" ;
and likewise: "one gram = one-thousand milligrams."].
____
We are given the weight, as a measure of mass;
in units of "grams" (g) ; and we are asked to convert this number into units of "milligrams (mg) ".
____
So: Convert our given: " 3 g " ; into units of "mg" ; as follows:
" Note:
" ;
And using the method of "dimensional analysis":
"
= [our answer] ? "
____
Note: The units of: "g" ["grams"] in the numerator of the left multiplicand of the expression—along with the units of "g" ["grams"] in the denominator of the second multiplicand in the expression—both cancel out to: " 1 " ;
→ {Since: "g/g" = "g ÷ g" = "1 ".].
Now, we can write the expression:
→ "
; → "(3)*(1,000 mg)" = " 3,000 mg" ; which is our answer.
The correct answer is: " 3,000 mg " ;
that is; "Three-thousand milligrams."
