Answer:

Use 3 times as many boxes of rice

Step-by-step explanation:

we know that

Using proportion

\frac{4}{13}\frac{boxes}{people}=\frac{x}{39}\frac{boxes}{people} \\ \\x=39*4/13\\ \\x=12\ boxes

original quantity of boxes ----->  4

boxes needed ----->  12

12=3*(4)

therefore

Use 3 times as many boxes of rice
