isRatio: 2:7:5

• Orange juice: 2x

,

• Pineapple juice: 7x

,

• Apple juice: 5x

Total fruit juice: 3L


\begin{gathered} 2x+7x+5x=3 \\ 14x=3 \\ x=(3)/(14) \end{gathered}

To know how many liters of pineapple juice (PJ)...


\begin{gathered} PJ=7x=7*(3)/(14)=(3)/(2) \\ PJ=(3)/(2)\approx1.5L \end{gathered}
