Question

Please help..., Iced tea mixture is in drink one as 9 tbsp mix to 4 cups of water and in drink 2 as 7 tbsp mix to 5 cups of water If I want a strong glass of iced tea do I use mix 1 or 2? Please help me explain.

Answer 1

You must use the first mix.

Explanation:

In the first mix, there are 9 tablespoons of iced tea for 4 cups. So, there must be exactly `(9/4)` tablespoons of iced tea in one cup(apply the Unitary Method).

Similarly, the second mix has 7 tablespoons of iced tea for 5 cups of water. So, 1 cup of water must contain `(7/5)` tablespoons of iced tea.

Now you must find which mix has a greater fraction. First, convert both fractions to a common denominator.
`(9xx5)/ (4xx5) = 45/20`
`(7xx4)/ (5xx4) = 35/20`

Clearly, `9/4` is greater. So, the first mix has a greater concentration of iced tea.
