Blueberries 79284

Lenka, Jane, and Michael collected blueberries in the ratio of 3:4:2. Lenka collected 4.5 liters of blueberries. How many blueberries did Jane and Michael collect?

Correct answer:

x =  9 l

Step-by-step explanation:

$$\begin{gathered} L=4.5\text{l} \\ L:J:M=3:4:2=3d:4d:2d \\ d=L/3=4.5/3=\frac{3}{2}=1.5 \\ J=4\cdot d=4\cdot 1.5=6\text{l} \\ M=2\cdot d=2\cdot 1.5=3\text{l} \\ x=J+M=6+3=9\text{l} \end{gathered}$$
