Withdraw 51 ml from the bag...
by: Anonymous

The previous answer is only partially right. You just didn't go far enough. 199 ml is what you should be left with in the bag (to get the correct strength), not withdraw from the bag.

See for yourself and follow the following process:

Set up the ratio equation:
(what we have) 983(mg strength):250(ml volume) = (what we need) 783(mg strength): X (ml volume)

Now, divide 783 by 983 = 0.796
Then multiply 0.796 by 250 mL and the answer is: X=199mL.

Finally, we subtract 199 from 250…

250-199= 51

Withdraw 51 ml from the bag.

983:250 = 783: X
divide 783 by 983 = 0.796
then multiply 0.796 by 250mL
and the answer is:
X=199mL
