Multiply and Divide Mixed Numbers and Complex Fractions · Exercise 73

Baking A recipe for chocolate chip cookies calls for $2 \frac{1}{4}$ cups of flour. Graciela wants to double the recipe.

ⓐ How much flour will Graciela need? Show your calculation. Write your result as an improper fraction and as a mixed number.
ⓑ Measuring cups usually come in sets with cups for $\frac{1}{8}, \frac{1}{4}, \frac{1}{3}, \frac{1}{2},$ and $1$ cup. Draw a diagram to show two different ways that Graciela could measure out the flour needed to double the recipe.

Its source prints no answer for this problem, so there's nothing to check against.
