Question

A certain drug is made from only two ingredients: compound A and compound B. There are
milliliters of compound A used for every
milliliters of compound B. If a chemist wants to make
milliliters of the drug, how many milliliters of compound A are needed?

Answer 1

Answer:

425 milliliters of compound A are needed

Step-by-step explanation:

We were told that $5$ milliliters of compound A and $6$ milliliters of compound B is needed to make the drug.

This means that each drug contains 11 milliliters of both compounds.

$\frac{935}{11}=85$ milliliters is the volume of each drug.

Therefore the chemist needed $5\times 85=425$ millilirteres of compound A.
