The strength ratio of each sports drink is 4:3.
Ratio can be defined as comparison of two or more similar quantities.
According to the given question Maria uses 2/3 cup of powdered mix for every 2 gallons of water.
Therefore the no. of cups of powdered mix per gallon in Maria's sports drink is
= (2/3)÷2
= (2/3)×(1/2)
= 2/6.
= 1/3 cups per gallon of sport drink.
In case of Franco the no. of cups of mix in his sport drink per gallon is
=(5/4)÷5
= 5/4×1/5
= 5/20
= 1/4 cups per gallon of sport drink.
∴ The strength of each sport drink is
= 1/3:1/4
= 12/3:12/4 ( LCM of 3,4 is 12 to remove the fractions)
= 4:3.
