There are 3 milliliters of compound A used for every 4 milliliters of compoundB. If a chemist wants to make 679 milliliters of the drug, how many milliliters of compound A are needed?

Answer 1

Answer:

291 milliliters

Explanation:

For every 7 milliliters of the drug, 3 milliliters are of compound A and 4 milliliters of compound B. So, using this ratio, we can calculate the milliliters of compound A for 679 milliliters of the drug as follows

$679\text{ milliliters}\times\frac{3\text{ milliliters}}{7\text{ milliliters of drug}}=291\text{ milliliters}$

Therefore, the answer is 291 milliliters of compound A.
