To find out how many donuts Ramon would make in 5 hours, we first need to find the unit rate of donuts per hour.
Ramon makes 33 donuts in 7 hours, so the unit rate is: \[ \text{Unit rate} = \frac{33 \text{ donuts}}{7 \text{ hours}} \approx 4.7142857 \text{ donuts per hour}. \]
Now, to find out how many donuts he would make in 5 hours, we multiply the unit rate by 5: \[ \text{Donuts in 5 hours} = 4.7142857 \text{ donuts/hour} \times 5 \text{ hours} \approx 23.5714285 \text{ donuts}. \]
Since we are looking for whole donuts, we round down to 23.
Therefore, the answer is: 23.
