You haven't told us enough, but it sounds like a ratio problem. For example, let's say compound A and compound B are in the ratio 3 to 2 and you want to make 15 ml of compound. Then compound A has 9 ml, and B has 6 ml. (9 + 6 = 15, and 9/6 are in the ratio 3 to 2.)

If you mean that parts a and b are used equally then you would divide the total number of milliliters by 2, thus cutting it in half. So, what is 704 divided by 2. You do the math ok.
Best wishes for a bright future!

You need more information to solve this problem, specifically how many units of A are needed to make 1 unit of B.
