Caroline collected 3 ¼ bags of recycling to take to the recycling center. ⅓ of the bags are glass bottles. How many bags will be filled with glass bottles?

Correct answer:

G =  1 ¹⁄₁₂ = 13/12

Step-by-step explanation:

$$\begin{gathered} B=3\frac{1}{4}=3+\frac{1}{4}=\frac{3\cdot 4+1}{4}=\frac{12+1}{4}=\frac{13}{4}=3\frac{1}{4}=3.25 \\ G=\frac{1}{3}\cdot B=\frac{1}{3}\cdot \frac{13}{4}=\frac{1\cdot 13}{3\cdot 4}=\frac{13}{12}=1\frac{1}{12}=1.0833 \end{gathered}$$
