Answer:
First, we need to determine how many pounds of food the ocicat eats in a week. There are 7 days in a week, so the ocicat eats $\frac 35$ pounds/day * 7 days/week = $\frac{7}{5}$ pounds/week.
Next, we need to divide the total amount of food in the bag by the amount of food that the ocicat eats in a week to determine how many weeks the bag of food will last. The bag of food weighs 19 1/2 pounds, so it will last for a total of 19 $1/2 pounds / $7/5 pounds/week = $33/7 weeks.
Finally, we need to divide the total number of weeks that the bag of food will last by the number of ocicats that the food will feed to determine how many ocicats the bag of food will feed for one week. The bag of food will feed $33/7 weeks / 1 week/ocicat = $33/7 ocicats.
Therefore, the 19 $1/2-pound bag of food will feed $33/7 ocicats for one week.
