Answer:
2 fl oz of salsa would be left in the jug.
Explanation:
Divide 6 fl oz into 128 fl oz. The remainder
128 fl oz
---------------- 21 1/3 bowls of salsa
6 fl oz
21 bowls would be completely filled with salsa, but the volume of 1/3 bowl would be left over and saved in the jug.
1/3 of a bowl translates into (1/3)(6 fl oz) = 2 fl oz
2 fl oz of salsa would be left in the jug.
