Answer 1

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.
