The Fruit Punch Recipe
Apple Juice      4 Liters
Mango Juice      2 Liters
Total            6 Liters



Lina wants to make 9 liters of fruit punch. This is larger than the standard recipe by factor of 9%2F6, or by 3%2F2. Be sure you understand this.

When you understand that, then
You want to INCREASE the standard recipe by the factor 3%2F2.

Apple Juice 4%283%2F2%29=6 liters
Mango Juice 2%283%2F2%29=highlight_green%283%29 Liters
