Brand A: 8 (fl oz) : $1:28

Brand B: 12:1.68

1) divide each side of the ratio

8:1.28 = 1:0.16

divide 8 by 8, and 1.28 by 8.

12: 1.68 = 1:0.14

divide each side by 12.

so, for brand A, for every one fluid oz it costs $0.16. for brand B, for every one fluid oz, it costs $0.14.

0.16-0.14 = 0.02

$0.02 per fluid oz
