Answer:

As a fraction, A is 3/8 concentrate in final product and B is 4/11.

A is, in other words, 33/88, and B is 36/88 concentrate in the final mixture.

So Mixture B is stronger, slightly.

Note that in order to make the fractions the same denominator, we had to 'expand' each fraction with the denominator of the other fraction. After that, the numbers are really easy to compare.
