A baker has three banana muffin recipes. Recipe A uses 3 bananas to make 12 muffins. Recipe B uses 5 bananas to make 24 muffins. Recipe C uses 11 bananas to make 48 muffins.
Rutendo tried to order the recipes from least to greatest by bananas per muffin, but he made a mistake. Here's his work:

\begin{aligned} \dfrac{12}{3}&=4\\\\ \dfrac{24}{5}&=4.8\\\\ \dfrac{48}{11}&\approx 4.36\\\\ \stackrel{\text{Least}}{\underbrace{4}_\text{Recipe A}} &< \underbrace{4.36}_\text{Recipe C} < \stackrel{\text{Greatest}}{\underbrace{4.8}_\text{Recipe B}} \end{aligned}
