Acertain drug is made from only two ingredients: compound a and compound b. there are 4 milliliters of compound a used for every 7 milliliters of compound b. if a chemist wants to make 671 milliliters of the drug, how many milliliters of compound a are needed?

answer:

there are 5 milliliters of compound a used for every 8 milliliters of compound b.

if a chemist wants to make 884 milliliters of the drug, how many milliliters of compound a are needed?

:

we know the ratio of a to b is 5: 8

let x = the multiplier

then

5x = amt of compound a

and

8x = amt of compound b

:

5x + 8x = 884

13x = 884

x = 884/13

x = 68 is the multiplier

therefore

5(68) = 340 millilters of compound a needed

:

:

confirm our answer. find the amt of b

8(68) = 544 ml of b

340 + 544 = 884
