Stefan has [tex]\(\frac{9}{2}\)[/tex] cups of oats. He uses [tex]\(\frac{13}{4}\)[/tex] cups to make granola bars for a camping trip. He saves the rest of the oats to feed his parrot, Coco. If Coco needs [tex]\(\frac{1}{4}\)[/tex] of a cup of oats each day, how many days can Stefan feed Coco with the oats he has left?

Let's break down the problem step by step to determine how many days Stefan can feed Coco with the remaining oats.

### Step 1: Determine the initial amount of oats.
Stefan starts with [tex]\( 4 \frac{1}{2} \)[/tex] cups of oats.

### Step 2: Convert the mixed number to an improper fraction.
[tex]\[ 4 \frac{1}{2} \) can be converted to an improper fraction: \[ 4 \frac{1}{2} = 4 + \frac{1}{2} = \frac{8}{2} + \frac{1}{2} = \frac{9}{2} \][/tex]

### Step 3: Determine the amount of oats used for granola bars.
Stefan uses [tex]\( 3 \frac{1}{4} \)[/tex] cups of oats to make the granola bars.

### Step 4: Convert the mixed number to an improper fraction.
[tex]\[ 3 \frac{1}{4} \) can be converted to an improper fraction: \[ 3 \frac{1}{4} = 3 + \frac{1}{4} = \frac{12}{4} + \frac{1}{4} = \frac{13}{4} \][/tex]

### Step 5: Subtract the amount of oats used from the initial amount.
[tex]\[ \frac{9}{2} - \frac{13}{4} \][/tex]

To subtract these fractions, we need a common denominator.

### Step 6: Convert both fractions to a common denominator.
The common denominator for 2 and 4 is 4.
[tex]\[ \frac{9}{2} = \frac{9 \times 2}{2 \times 2} = \frac{18}{4} \][/tex]

So now we can subtract:
[tex]\[ \frac{18}{4} - \frac{13}{4} = \frac{18 - 13}{4} = \frac{5}{4} \][/tex]

### Step 7: Determine how many days Stefan can feed Coco.
Coco needs [tex]\( \frac{1}{4} \)[/tex] cup of oats each day. We need to figure out how many [tex]\( \frac{1}{4} \)[/tex]-cup servings are in [tex]\( \frac{5}{4} \)[/tex] cups of oats.

To do this, divide the remaining oats by the daily amount:
[tex]\[ \text{Number of days} = \frac{\frac{5}{4}}{\frac{1}{4}} = \frac{5}{4} \times \frac{4}{1} = \frac{5 \times 4}{4 \times 1} = \frac{20}{4} = 5 \][/tex]

### Final Answer
Stefan can feed Coco for [tex]\(\boxed{5}\)[/tex] days with the oats he has left.
