Those ratios for "requires" are not the same. One of those in your description needs to be changed. How much of A and B are available?
8 to 12 is the same as 2 to 3. If a mixture WANTED is 24 ounce of A and 30 ounce of B, then for 30 ounce of B, the amount of A to use would be %282%2F3%29%2A30=20. One mixture which can be made then is 20 ounce of A with 30 ounce of B.

On the other hand, if chosen were 24 ounce of A, then the amount of B to use would be %283%2F2%29%2A24=36 ounce. Not possible, because only 30 ounce of B available.

A mixture of 50 ounces of "chemical compound" could be made:
20 ounce of chemical A and 30 ounce of chemical B.
