Answer:
The recipe will make 7.2 quarts of punch.
Step-by-step explanation:
A punch recipe calls for 3 liters of ginger ale and 1.5 liters of tropical fruit juice.
Then the recipe will make 4.5 liters of punch, obtained by the sum of ginger ale and tropical fruit juice.
The ration is the comparison of two quantities and is measured from the division of two values, then: [tex]\frac{a}{b}[/tex].
The proportion is the equality between two or more ratios. That is, [tex]\frac{a}{b}=\frac{c}{d}[/tex] equals a proportion.
In this case, being 1 L= 1.6 quarts, you have:
[tex]\frac{1.6 quarts}{1 L}=\frac{x}{4.5 L}[/tex]
Solving:
[tex]x=4.5 L*\frac{1.6 quarts}{1 L}[/tex]
x= 7.2 quarts
So, the recipe will make 7.2 quarts of punch.
