Answer 2

If a patient needs to take 20mg of medication at 20mg per ml, how many ml should be given?

Answer 3

Since there are 20mg per ml only 1ml\(\large(\frac{20mg}{20mg.ml^{-1}})\) should be given. Understand?

Answer 4

Since there is 20mg per ml only 1ml\(\large(\frac{20mg}{20mg.ml^{-1}})\) should be given.
Likewise 35mg is needed, but there is 70mg per ml so \(\large(\frac{35mg}{70,g.ml^{-1}})\) should be given.
