Explanation:

Step1: Find sauce per serving

$\text{Sauce per serving} = \frac{15}{5} = 3$ cups

Step2: Calculate sauce for 7 servings

$\text{Total sauce} = 3 \times 7 = 21$ cups

Step3: Find oregano per serving

First, convert $2\frac{1}{2}$ to $\frac{5}{2}$.
$\text{Oregano per serving} = \frac{\frac{5}{2}}{5} = \frac{1}{2}$ tsp

Step4: Calculate oregano for 7 servings

$\text{Total oregano} = \frac{1}{2} \times 7 = \frac{7}{2} = 3\frac{1}{2}$ tsp
