Which measure correctly completes the statement 3,271.5 milligrams = ? grams A: 0.032715 grams B: 3.2715 grams C: 327.15 grams D: 32,7150 grams
A: 0.032715 grams
Which measure correctly completes the statement 321.517L = ? mL A: 0.0321517 mL B: 3,215,170 mL C: 321,517 mL D: 32,151.7 mL
To convert milligrams to grams, you divide the value in milligrams by 1000.
Therefore, 3,271.5 milligrams = 3,271.5 / 1000 = 3.2715 grams.
So, the correct measure is option B: 3.2715 grams.
To convert milligrams to grams, we divide by 1000 since there are 1000 milligrams in one gram.
So, to find the correct measure to complete the statement 3,271.5 milligrams = ? grams, we divide 3,271.5 by 1000.
Let's go through the options:
A: 0.032715 grams
To get this answer, we would need to divide 3,271.5 by 1000. However, doing the math, we find that 3,271.5 divided by 1000 is equal to 3.2715, not 0.032715. So option A is incorrect.
B: 3.2715 grams
To get this answer, we do not need to perform any calculations. This is the exact measure in grams of 3,271.5 milligrams, as we have converted milligrams to grams. So option B is the correct answer.
C: 327.15 grams
To get this answer, we would need to multiply 3,271.5 by 1000 instead of dividing by 1000. However, multiplying would result in a larger number, while we want to convert milligrams to grams, which means the resulting value should be smaller. So option C is incorrect.
D: 32,715 grams
To get this answer, we would need to multiply 3,271.5 by 1000. However, as mentioned before, multiplying would result in a larger number, while we want to convert milligrams to grams, which means the resulting value should be smaller. So option D is incorrect.
Therefore, the correct measure that completes the statement 3,271.5 milligrams = ? grams is B: 3.2715 grams.
