1 5/8 = 13/8
(13/8)/14 = .116 or 13/112
.116 (26) = 3.016 or 169/56

Answer:

  3 1/56 cups

Step-by-step explanation:

Apparently, you're to assume that the amount of food is supposed to be proportional to weight. If x is the amount of food for the 26-pound dog, then ...

  cups/weight = (1 5/8)/14 = x/26

Multiplying by 26 we have ...

  x = (26)(13/8)/14 = 338/112 . . . cups

  x = 3 1/56 cups ≈ 3.02 cups

About 3.02 cups of the same type of food should be fed to a 26-pound dog.
