Explanation:

Step1: Find per-serving rhubarb

First, calculate rhubarb per serving using 10 servings:
$\frac{7\frac{1}{2}}{10} = \frac{\frac{15}{2}}{10} = \frac{15}{20} = \frac{3}{4}$ cups per serving
For 5 servings: $5 \times \frac{3}{4} = \frac{15}{4} = 3\frac{3}{4}$

Step2: Find unknown servings for rhubarb

Use $\frac{3}{4}$ cups rhubarb: $\frac{3/4}{3/4} = 1$ serving

Step3: Find 20 servings milk

Milk per serving: $\frac{2\frac{1}{2}}{10} = \frac{5/2}{10} = \frac{1}{4}$ cups per serving
For 20 servings: $20 \times \frac{1}{4} = 5$ cups

Step4: Find 15 servings ice cream

Ice cream per serving: $\frac{6\frac{1}{4}}{10} = \frac{25/4}{10} = \frac{5}{8}$ pints per serving
For 15 servings: $15 \times \frac{5}{8} = \frac{75}{8} = 9\frac{3}{8}$

Step5: Find 11 servings orange zest

Zest per serving: $\frac{1\frac{1}{4}}{10} = \frac{5/4}{10} = \frac{1}{8}$ teaspoons per serving
For 11 servings: $11 \times \frac{1}{8} = \frac{11}{8} = 1\frac{3}{8}$

Answer:

Missing Cell Location	Value
Rhubarb (5 servings)	$3\frac{3}{4}$
Milk (20 servings)	$5$
Strawberry Ice Cream (15 servings)	$9\frac{3}{8}$
Orange Zest (11 servings)	$1\frac{3}{8}$
