To set up the proportion, we can write it as follows:
\[ \frac{33 \text{ donuts}}{7 \text{ hours}} = \frac{x \text{ donuts}}{5 \text{ hours}} \]
Now, we can cross-multiply to solve for \( x \):
\[ 33 \times 5 = 7 \times x \]
This simplifies to:
\[ 165 = 7x \]
Now, divide both sides by 7 to solve for \( x \):
\[ x = \frac{165}{7} \approx 23.57 \]
Since we want the number of whole donuts, we round down to 23. Therefore, the complete proportion looks like this:
\[ \frac{33}{7} = \frac{23}{5} \]
Deborah will make 23 whole donuts in 5 hours.
