Question 752954: A certain drug is made from only two ingredients: compound A and compound B. There are 7 milliliters of compound A used for every 4 milliliters of compound B. If a chemist wants to make 627 milliliters of the drug, how many milliliters of compound A are needed?

This is a ratio question.
7 ml of Cmpd A: 4 ml of Cmpd B
Add 7 + 4 = 11
So 7/11 of 627 ml will be Cmpd A
= 399 ml of Cmpd A.
Hope this helps
:-)
