Answer:
 Moses's mixture is more acidic
Explanation:
For the purpose here, acidity can be measured as the ratio of acid to water. We want to determine the comparison of ...
 Bao = 4/26
and
 Moses = 3/17
__
Multiplying both ratios by (26×17), we get ...
 Bao ~ 4(17) = 68
 Moses ~ 3(26) = 78
Then the acidity compares as ...
 68 < 78 ⇔ 4/26 < 3/17
Moses's mixture is more acidic.
