Recipe ingredients

Monica's cookie recipe calls for Three-fourths of a cup of flour. Her mother's recipe calls for Two-thirds as much as Monica's. How many cups of flour does her mother's recipe require?

Final Answer:

r =  0.5

Step-by-step explanation:

$$\begin{gathered} M=\frac{3}{4}=0.75 \\ r=\frac{2}{3}\cdot M=\frac{2}{3}\cdot \frac{3}{4}=\frac{2\cdot 3}{3\cdot 4}=\frac{6}{12}=\frac{1}{2}=0.5 \end{gathered}$$
