Problem page a certain drug is made from only two ingredients: compound a and compound b. there are 5 milliliters of compound a used for every 6 milliliters of compound b. if a chemist wants to make 935 milliliters of the drug, how many milliliters of compound a are needed?

425 mm

Step-by-step explanation:

The ratio of compound A to compound B is 5 is to 6.

So, we can say that the total ratio is of 11 parts (5+6=11).

If the chemist wants a total of 935 mm of the drug, then each of the 11 parts are worth:

From the ratio, we know that Compound A is 5 parts. So:

425 mm of Compound A is needed.
