To find out how many donuts Ramon makes in one hour, we can calculate the unit rate of donuts per hour.
Ramon makes 33 donuts in 7 hours.
Now, let's find the rate of donuts per hour:
\[ \text{Rate} = \frac{33 \text{ donuts}}{7 \text{ hours}} \approx 4.7143 \text{ donuts per hour} \]
Now that we have the rate, we can determine how many donuts he would make in 5 hours by multiplying the hourly rate by 5:
\[ \text{Donuts in 5 hours} = 4.7143 \text{ donuts/hour} \times 5 \text{ hours} \approx 23.5715 \text{ donuts} \]
Since we are looking for the number of whole donuts, we round down as we cannot have a fraction of a donut.
Thus, the number of whole donuts Ramon would make in 5 hours is:
\[ \boxed{23} \]
